Introduction
Introduction
WARNING: RF Radiation Hazard - This stabilized antenna system is designed to be used with
transmit/receive equipment manufactured by others. Refer to the documentation supplied by
the manufacturer which will describe potential hazards, including exposure to RF radiation,
associated with the improper use of the transmit/receive equipment. Note that the
transmit/receive equipment will operate independently of the stabilized antenna system.
The ultimate responsibility for safety rests with the facility operator and the individuals
who work on the system.
1.1.
General Description of system
Your Series 00 system is a fully stabilized antenna that has been designed and manufactured so as to be
inherently reliable, easy to maintain, and simple to operate. Except for start-ups, or when changing to
operate with different transponders or satellites, the equipment essentially permits unattended
operation.
1.2.
Purpose
This shipboard Transmit-Receive (TXRX) system provides you with two-way satellite voice/data
communications while underway on an ocean-going vessel. This can be used to provide a wide variety
of telephone, fax and data applications. Your Antenna system can transmit to and receive from any
desired satellite which has adequate signal coverage in your current geographic area. Your antenna may
be fitted with appropriate Transmit & Receive RF Equipment and appropriate Feed to allow you to
operate in linear or circular polarization mode at C-Band frequencies. This input will be distributed to
your satellite modem and then to all of your other below decks equipment.
1.3.
System Components
Your TXRX system consists of two major groups of equipment; an above-decks group and a below-decks
group. Each group is comprised of, but is not limited to, the items listed below. All equipment
comprising the Above Decks is incorporated inside the radome assembly and is integrated into a single
operational entity. For inputs, this system requires only an unobstructed line-of-sight view to the
satellite, Gyro Compass input and AC electrical power.
For more information about these components, refer to the Basic System Information section of this
manual.

reflector.
The ultimate responsibility for safety rests with the facility operator and the
individuals who work on the system.
2.1.
System Power-up
Turn the power switch mounted in the aft louvered panel of the antenna pedestal ON. This will energize
the antenna pedestal and the RF equipment.
2.2.
Antenna Initialization
A functional operation check can be made on the antenna stabilization system by observing its behavior
during the 4 phases of initialization.
Turn the pedestal power supply ON. The PCU will initialize the stabilized portion of the mass to be level
with the horizon and at a prescribed Azimuth and Elevation angles. The antenna will go through the
specific sequence of steps (listed below) to initialize the antenna. These phases initialize the level cage,
elevation, cross-level and azimuth to predetermined starting positions.
Initialization is completed in the following phases, each phase must complete properly for the antenna to
operate properly (post-initialization).
1. Level Cage is driven CCW, issuing extra steps to assure that the cage is all the way to the
mechanical stop. Then the Level cage will be driven exactly 45.0 degrees CW.
2. Elevation axis activates - Input from the LV axis of the tilt sensor is used to drive the Elevation of
the equipment frame to bring the tilt sensor LV axis to level (this results in the dish being at an
elevation angle of 45.0 degrees).
3. Cross-Level axis activates - Input from the CL axis of the tilt sensor is used to drive Cross-Level
of the equipment frame to bring the cross-level axis of the tilt sensor to level (this results in the
tilt of the Cross-Level Beam being level).
4. Azimuth axis activates - Antenna drives in azimuth until the “Home Flag” signal is produced.
This signal is produced by a Home Switch hitting a cam or by a Hall Effect sensor in close
proximity to a Magnet.
This completes the phases of initialization. At this time the antenna elevation should 45.0 degrees and
Relative azimuth should be at be at home flag (home switch engaged on the home flag cam).
2-1
Operation
14600-75 C-Band TXRX
If any of theses steps fail, or the Antenna Control Unit reports model number as "xx97" re-configure the
PCU as described in section the Setup section of this manual. If initialization still fails, refer to the
troubleshooting section of this manual.
2.3.
Antenna Stabilization
After initialization has completed, real-time stabilization of the antenna is an automatic function of the
PCU.
2.4.
Stabilized Pedestal Assembly Operation
Operation of the stabilized antenna Pedestal Control Unit (PCU) is accomplished remotely by the
Antenna Control Unit (ACU). Refer to the Operation section of the Antenna Control Unit manual for
more specific operation details. There are no other operating instructions applicable to the pedestal
assembly by itself.
2.5.
Tracking Operation
Tracking optimizes the antenna pointing, in very fine step increments, to maximize the level of the
satellite signal being received. The mode of tracking used in this antenna is a variation of Conical
Scanning called DishScan.
DishScan continuously drives the antenna in a very small circular pattern at 60 RPM. The ACU evaluates
the received signal throughout each rotation to determine where the strongest signal level is (Up, Right,
Down or Left) and issues the appropriate Azimuth and/or Elevation steps to the antenna, as needed.
You cannot control tracking from the pedestal itself. Refer to the ACU manual for tracking operation
information.
2.6.
Antenna Polarization Operation
Linear feeds are equipped with a polarization motor and potentiometer feedback and are controlled from
the Antenna Control Unit. When using a linear polarized feed, you should set the POL TYPE parameter
in the ACU to 0072 (Auto-Polarization – this mode is the default polarization mode of operation from the
ACU).
Circular feeds do NOT require periodic polarization adjustment as the ship travels, but must be
assembled correctly for LHCP or RHCP polarization operation (refer to the maintenance section of this
manual). When using a circular polarized feed, you should set the POL TYPE parameter in the ACU to
0000.
2.7.
RF Equipment
The RF Equipment is not operated or controlled by the antenna pedestal or Antenna Control Unit. Refer
to the Paradise manuals for the RF Equipment provided with your system.
You may also have Paradise software installed in a below-decks computer which is used to control the
RF equipment that is mounted on your antenna pedestal.
2.8.
Radome Assembly Operation
When operating the system it is necessary that the radome access hatch (and/or side door) be closed
and secured in place at all times. This prevents rain, salt water and wind from entering the radome.
Water and excessive condensation promote rust & corrosion of the antenna pedestal. Wind gusts will
disturb the antenna pointing.
There are no other operating instructions applicable to the radome assembly by itself.

2.9.
Operation
FCC TX Mute Function
FCC TX Mute function provides a transmit inhibit, or mute, signal to the Satellite Modem to disable
transmit whenever the antenna is blocked, searching, targeting or is mispointed 0.5 degrees from peak
satellite position. This functionality is provided by software in the ACU & PCU. Hardware wiring
connection between the ACU Terminal Mounting Strip and the Satellite Modem and proper setup of the
ACU “SYSTEM TYPE” parameter are also required for this function to operate properly.
After being properly installed and setup correctly the FCC TX Mute function operation is automatic,
therefore, requires no operator intervention. Refer to the Installation and Setup chapters in this manual
and in your Antenna Control Unit manual.
2.10. Switching Active/Standby RF Equipment
2.10.1. Transmit Switching
Please refer to your Paradise manual(s) for procedures you will use to remotely control the
Transmit path RF Equipment mounted on the antenna pedestal.
2.10.2. Receive Path Switching
The receive path switching is controlled through the Antenna Control Unit. This band selections
displayed are set by the TRACK DISP parameter. Your default value is 0060. Press the NEXT
key on the front panel of the ACU to access the TRACKING window. Select the appropriate
receive signal path by pressing the DOWN arrow as needed (refer to the Operation chapter of
the ACU manual MODE – TRACKING – BAND SELECTION). The TRACKING display selections
are:
LNB A
selects receive from LNB A
LNB B
selects receive from LNB B
LNB A
selects receive from LNB A
LNB B
selects receive from LNB B
This selection remotely controls the Shielded Polang Relay Assembly to actuate an RF Switch to
select which low noise block converter is providing receive signal through the dual channel
rotary joint to the below decks equipment.

Basic System Information
Basic System Information
This section is intended to provide you with some basic information about satellites, your antenna system and
some of the other equipment that may be used in your system configuration.
3.1.
Satellite Basics
The satellites are in orbit at an altitude of 22,754 miles and are positioned directly above the equator.
Their orbital velocity matches the Earth’s rotational speed, therefore, each appears to remain at a fixed
position in the sky (as viewed from your location).
Your antenna can be used with any of the satellites in this orbit that have a strong enough receive signal
level. Your antenna is capable of being fitted with a Linear or Circular feed assembly. The feed may be
designed to operate at C-Band frequencies, Ku-Band frequencies or be capable of operation in both
bands. With the correct feed assembly you will be able to receive the linear or circular signal at the
specific frequency range of the desired satellite.
3.1.1. C-Band Receive Frequency (3.7-4.2GHz)
At these frequencies the signal from the satellite travels only in a straight line and is affected by
weather changes in the atmosphere. There are several conditions that can cause a temporary
loss of satellite signal, even within an area where the signal level is known to be adequate. The
most common of these normal temporary losses are blockage and rain fade. They will
interrupt services only as long as the cause of the loss persists.
3.1.2. Blockage
Blockage is loss due to an object in the path of the signal from the satellite to the dish. If an
object that is large and dense is positioned in the path of the signal from the satellite, it will
prevent sufficient signal from arriving at the dish. The signal can not bend around, or penetrate
through, these objects and the reception will be degraded or completely interrupted. The dish is
actively driven to remain pointed at the satellite (toward the equator) so, as the ship turns a mast
or raised structure of your ship may become positioned between the satellite and the dish.
Blockage may also be caused a anything standing near the radome, tall mountains, buildings,
bridges, cranes or other larger ships near your ship. Moving or rotating the ship to position the
antenna where it has an unobstructed view to the desired satellite will restore the antennas’
ability to receive the satellite signal.
3.1.3. Rain Fade
Atmospheric conditions that may cause sufficient loss of signal level include rain, snow, heavy
fog and some solar activities (sun spot and flare activity). The most common of these is
referred to as “rain fade”. Rain drops in the atmosphere reduce the signal from the satellite.
The heavier the rain the higher the amount of signal loss. When the amount of loss is high
enough, the antenna will not be able to stay locked onto the satellite signal. When the amount
of rain has decreased sufficiently, the antenna will re-acquire the satellite signal. In a strong
signal area, rain fall of about four inches per hour will cause complete loss of signal. In weaker
signal areas the effects would be more pronounced.
3-1
Basic System Information
14600-75 C-Band TXRX
3.1.4. Signal level
The level of the receive signal is dependant upon how powerful the transmission is, how wide
the signal beam is, and what the coverage area is. Focusing the signal into a narrower beam
concentrates its energy over a smaller geographic area, thereby increasing the signal level
throughout that area of coverage. This makes it possible for you to use a smaller antenna size to
receive that satellite signal. The antenna system must be geographically located in an area
where the signal level from the satellite meets (or exceeds) the minimum satellite signal level
required for your size of antenna (refer to the Specifications section of this manual) to provide
suitable reception. This limits the number of satellites that can be used and the geographic
areas where the ship can travel where the signal level is expected to be strong enough to
continue providing uninterrupted reception. When traveling outside this minimum signal
coverage area, it is normal for the system to experience an interruption in its ability to provide
the desired satellite services until entering (or re-entering) an area of adequate signal level.
3.1.5. Satellite Footprints
The focused beam(s) from the satellites are normally aimed at the major land masses where
there are large population centers. Footprint charts graphically display the signal level expected
to be received in different geographic locations within the area of coverage. The signal will
always be strongest in the center of the coverage area and weaker out toward the outer edges
of the pattern. The coverage areas are intended to be a guide to reception, however, the actual
coverage area and signal level and vary. Also the signal strength is affected by weather.
3.1.6. Satellite Circular Polarization
When the satellite you are using is transmitting circular polarized satellite transmissions, you will
need to set up your feed assembly for RHCP or LHCP to match the “polarization” of your
antenna to the satellite. No other adjust is need on the “polarization” during antenna operation
3.2.
Antenna Basics
The following information is provided to explain some of the basic functions of the antenna:
3.2.1. Unlimited Azimuth
Azimuth rotation of the antenna is unlimited (no mechanical stops). Azimuth drive, provided by
the azimuth motor, is required during stabilization, searching and tracking operations of the
antenna. When the ship turns, azimuth is driven in the opposite direction to remain pointed at
the satellite. The actual azimuth pointing angle to the satellite is determined by your latitude &
longitude and the longitude of the satellite. It is important to know that the antenna should be
pointed (generally) toward the equator.
The azimuth angle to the satellite would be 180 degrees true (relative to true north) if the
satellite is on the same longitude that you are on. If the satellite is east, or west, of your
longitude the azimuth will be less than, or greater than 180 degrees respectively.
When checking for blockage you can visually look over the antenna radome toward the equator
to see if any objects are in that sighted area. If you are not able to find any satellites it may also
be useful to remove the radome hatch to visually see if the dish is aimed the correct direction
(towards the equator).

14600-75 C-Band TXRX
Basic System Information
3.2.2. Elevation
In normal operation the elevation of the antenna will be between 00.0 (horizon) and 90.0 (zenith).
The antenna can physically be rotated in elevation below horizon and beyond zenith to allow for
ship motion. Elevation drive, provided by the elevation motor, is required during stabilization,
searching and tracking operations of the antenna. The actual elevation pointing angle to the
satellite is determined by your latitude & longitude and the longitude of the satellite. In general
terms the elevation angle will be low when you are at a high latitudes and will increase as you
get closer to the equator.
Additionally, from any given latitude, the elevation will be highest when the satellite is at the
same longitude that you are on. If the satellite is east, or west, of your longitude the elevation
angle will be lower.
3.2.3. The 3.7 meter antenna
The signal from the satellite bounces off of the main reflector, is focused up to and reflects off
of the sub-reflector and is focused down into the feed assembly. It then passed through the
phase card polarizer where the circular polarization is converted into linear and is passed into the
OMT (Ortho Mode Transducer). The receive signal from the polarizer is sent out the RX Port of
the OMT. The transmit signal enters the TX port on the OMT is converted to circular by the
phase card polarizer, emits out of the feed, reflects off of the sub-reflector and then off of the
main reflect and is radiated out to the satellite.
Satellite Signal
3.2.3.1.
Feed Assembly
The Suman 3.7 meter feed is circular polarized. You must manually adjust the position
of the OMT on the Polarizer to select either LHCP Left Hand circular polarization or
RHCP Right Hand polarization required by the satellite.
The receive port of the OMT has a 60 dB TX reject filter to protect the LNA.
3.2.4. Antenna polarization
The Suman 3.7 meter feed is circular polarized. You must manually align the position of the
OMT on the Polarizer to set the Transmit (or Receive) port to the either Left Hand Circular
Polarity (LHCP) or Right Hand Circular Polarity (RHCP) as required by the satellite.
3-3
Basic System Information
14600-75 C-Band TXRX
3.2.5. Stabilization
Your antenna is stabilized in all three axes of motion. Stabilization is the process of de-coupling
the ships’ motion from the antenna. Simply put, this allows the antenna to remain pointed at a
point in space while the boat turns, rolls or pitches under it. To accomplish this, the Pedestal
Control Unit (PCU) on the antenna pedestal assembly senses the motion and applies drive to the
appropriate motor(s) in opposition to the sensed motion. Azimuth (AZ), Elevation (EL) and CrossLevel (left-right tilt) are actively stabilized automatically by the PCU as part of its normal
operation.
3.2.6. Search Pattern
Whenever the desired satellite signal is lost (such as when the antenna is blocked) the Antenna
Control Unit will automatically initiated a Search to re-acquire the desired signal.
Search is conducted in a two-axis pattern consisting of alternate movements in azimuth and
elevation. The size and direction of the movements are increased and reversed every other time
resulting in an expanding square pattern.
When the antenna is able to re-acquire the desired signal the ACU will automatically stop
searching and begin Tracking the signal to optimize the pointing of the antenna to get the
highest signal level from the satellite.
3.2.7. Tracking Receiver – Single Channel Per Carrier Receiver
The SCPC Narrow Band Receiver located in the Antenna Control Unit (ACU) is used to acquire,
identify and track a narrow band carrier, or beacon signal, or the desired satellite. When properly
setup, the settings for the satellite are saved to expedite future acquisition of the desired
satellite. The system must have adequate satellite signal level to stop searching (and begin
tracking the acquired satellite).
3.2.8. Tracking
Your Antenna Control Unit actively optimizes the pointing of the dish for maximum signal
reception. This process is called tracking and is accomplished by continuously making small
movements of the dish while monitoring the level of the received signal. Evaluation of this
information is used to continuously move the stabilization point toward peak satellite signal
reception. These minor pointing corrections keep the signal level “peaked” as part of normal
operation.
3.3.
Components of the System Configuration
The following text provides a basic functional overview of the system components and component
interconnection as referred to in the simplified block diagram (see drawings section of this manual).
3.3.1. Antenna ADE Assembly
The Above Decks Equipment consists of an Antenna Pedestal inside a Radome assembly. The
pedestal consists of a satellite antenna dish & circular feed assembly, redundant RF components
and RF path switching components mounted on a stabilized antenna pedestal. The radome
provides an environmental enclosure for the antenna pedestal assembly inside it. This keeps
wind, water condensation and salt-water spray off the antenna pedestal assembly. This
prevents damage and corrosion that would shorten the expected life span of the equipment.
Two coaxial cables are connected from the antenna radome assembly to the below decks
equipment. One of these cables includes the Antenna Control signaling and IF, the other cable
carries the other IF signal.
3-4
14600-75 C-Band TXRX
Basic System Information
These cables ultimately provide the input/output signals into/out of the satellite modem.
3.3.2. Antenna Control Unit
The Antenna Control Unit allows the operator to control and monitor the antenna pedestal with
dedicated function buttons, LED’s and a 2 line display. The ACU and its Terminal Mounting Strip
are normally mounted in a standard 19” equipment rack. The ACU should be mounted in the
front of the equipment rack where it is easily accessible. The Terminal Mounting Strip is
normally mounted on the rear of the equipment rack. It is recommended that the antenna
control unit be mounted near the Satellite modem location where you can see the LED
indicators while you are controlling the antenna.
The Antenna Control Unit is connected to the antenna, ships Gyro Compass and Satellite
modem.
Figure 3-1 Antenna Control Unit
The Antenna Control Unit (ACU) communicates via an RS-422 full duplex data link with the
Pedestal Control Unit (PCU) located on the antenna. This control signal to/from the antenna is on
the Coax cable along with the L-Band Receive IF from the LNB. The Pedestal Control Unit
stabilizes the antenna against the ship's roll, pitch, and turning motions. The ACU is the operator
interface to the PCU and provides the user with a choice of positioning commands to point the
antenna, search commands to find the satellite signal and tracking functions to maintain
optimum pointing. The operator may choose to work from either the front panel, using the M&C
Port in conjunction with DacRemP remote diagnostic software, or the built in Ethernet port and a
internal HTML page using a standard internet browser .
3.3.3. Above Decks AC Power Supply
Power for the Antenna Pedestal and RF Equipment (TX/RX Systems ONLY) - The AC Voltage
required for the 14600 antenna is 220 VAC due to the current draw required to operate the
antenna pedestal and all of the RF Equipment mounted to it. Total power consumption will
depend on the number of type of transceivers and amplifiers used. Refer to the Paradise
equipment manuals to determine the total MAX power consumption your RF equipment. The
pedestal itself requires only 290 watts.
Sea Tel Recommends that the AC voltage source be well regulated and surge protected. An
Uninterrupted Power Supply is preferred, usually installed (below decks) to provide adequately
regulated power for the antenna pedestal, especially if RF Equipment is installed on the
pedestal.
Marine Air Conditioner Unit (TX/RX Systems ONLY) - If a marine air conditioner is included with
your system, the AC voltage source should be from a separate AC Power breaker source
than the antenna pedestal. AC power for the air conditioner should be well regulated and
surge protected, but does NOT need to from an Uninterrupted Power Supply. Refer to the
marine air conditioner manual for its’ power requirements and consumption specifications.

no one should be allowed anywhere within the radiated beam being emitted from the
reflector.
The ultimate responsibility for safety rests with the facility operator and the
individuals who work on the system.
4.2.
Site Survey
The radome assembly should be installed at a location aboard ship where:
1. The antenna has a clear line-of-sight to as much of the sky (horizon to zenith at all bearings) as is
practical.
2. Direct radiation into the antenna from ships radar, especially high power surveillance radar
arrays, is minimized. The radome should be as far away from the ships Radar as possible and
should NOT be mounted on the same plane as the ships Radar (so that it is not directly in the
Radar beam path).
3. The radome should be as far away from the ships high power short wave (MF & HF) transmitting
antennas as possible.
4. The Above Decks Equipment (ADE) and the Below Decks Equipment (BDE) should be positioned
as close to one another as possible. This is necessary to reduce the losses associated with long
cable runs.
5. The mounting location is rigid enough that it will not flex, or sway, in ships motion or vibration. If
the radome is to be mounted on a raised pedestal, it MUST have adequate gussets, or be well
guyed, to prevent flexing or swaying in ships motion.
If these conditions cannot be entirely satisfied, the site selection will inevitably be a “best” compromise
between the various considerations.

4.10. During Power-Up Of The ADE
4.10.1. Initialization
Turn the pedestal power supply ON. The PCU will initialize the stabilized portion of the mass to
be level with the horizon and at a prescribed Azimuth and Elevation angles. The antenna will go
through the specific sequence of steps to initialize the level cage, elevation, cross-level and
azimuth to predetermined starting positions. Each phase must complete properly for the
antenna to operate properly (post-initialization). Refer to the initialization text in the
Troubleshooting section in this manual. Observe the Initialization of the antenna pedestal.
If any of these steps fail, or the ACU reports model "xx97", re-configure the PCU as described in
the Setup section of this manual. If initialization still fails, this indicates a drive or sensor
problem, refer to the Troubleshooting section.
4.10.2. Home Flag Position
Note the approximate position of the antenna relative to the bow of the ship while it is at the
home switch position. This information will be used later to calibrate the relative position display
of the antenna.

Setup
Setup
Below are basic steps to guide you in setting up the ACU for your specific antenna pedestal. Assure that the
Antenna Pedestal (ADE) has been properly installed before proceeding. Refer to the Setup section of you ACU
manual for additional parameter setting details.
5.1.
Operator Settings
Refer to the Operation chapter of this manual to set the Ship information. Latitude and Longitude should
automatically update when the GPS engine mounted above decks triangulates an accurate location, but
you may enter this information manually to begin. If your gyro source is providing Heading information in
any format other than NMEA-0183 format, you will have to enter in the initial Ship’s Heading position,
the Gyro Compass will then keep the ACU updated.
Set the Satellite information, for the satellite you will be using. The receiver settings are especially
important. At this point you should be able to target the desired satellite. Continue with the setup steps
below to optimize the parameters for your installation.
5.2.
Optimizing Targeting
First, assure that all of your Ship & Satellite settings in the ACU are correct. Target the desired satellite,
immediately turn Tracking OFF, and record the Azimuth and Elevation positions in the “ANTENNA“
display of the ACU (these are the Calculated positions). Turn Tracking ON, allow the antenna to
“Search” for the targeted satellite and assure that it has acquired (and peaks up on) the satellite that you
targeted. Allow several minutes for the antenna to “peak” on the signal, and then record the Azimuth
and Elevation positions while peaked on satellite (these are the Peak positions). Again, assure that it has
acquired the satellite that you targeted!
Subtract the Peak Positions from the Calculated Positions to determine the amount of Trim which is
required. Refer to the ACU Setup information to key in the required value of Elevation Trim. Continue
with Azimuth trim, then re-target the satellite several times to verify that targeting is now driving the
antenna to a position that is within +/- 1.0 degrees of where the satellite signal is located.
EXAMPLE: The ACU targets to an Elevation position of 30.0 degrees and an Azimuth position of 180.2
(Calculated), you find that Peak Elevation while ON your desired satellite is 31.5 degrees and Peak
Azimuth is 178.0. You would enter an EL TRIM value of –1.5 degrees and an AZ TRIM of +2.2 degrees.
After these trims values had been set, your peak on satellite Azimuth and Elevation displays would be
very near 180.2 and 30.0 respectively.
5-1
Setup
14600-75 C-Band TXRX
5.3.
Calibrating Relative Antenna Position (Home Flag Offset)
During initialization, azimuth drives the CW antenna until the Home Switch is contacted, which
“presets” the relative position counter to the value stored in the Home Flag Offset. This assures that
the encoder input increments/decrements from this initialization value so that the encoder does not have
to be precision aligned.
The Home Switch is a micro switch with a roller arm which is actuated by cam mounted on the azimuth
driven sprocket, or it is a hall sensor which is actuated by a magnet mounted on the azimuth driven
sprocket, which produces the “Home Flag” signal.
The Home Flag Offset is a value saved in NVRam (Non-Volatile RAM) in the PCU. This value is the
relative position of the antenna when the home switch is engaged. Presetting the counter to this value
assures that when the antenna is pointed in-line with the bow of the ship the counter will read 000.0
Relative (360.0 = 000.0).
In most cases when the antenna stops at the
home flag, it will be pointed in-line with the
Bow of the ship. In these cases Home Flag
Offset (HFO) should be set to zero. When
“Optimizing Targeting” small variations (up to
+/- 5.0 degrees) in Azimuth can be corrected
using If it AZ TRIM as described in the
Optimizing Targeting procedure above.
Large variations in Azimuth position indicate
that the Relative position is incorrect and
should be “calibrated” using the correct HFO
value instead of an Azimuth Trim offset. This is
especially true if sector blockage mapping is
used.
If the antenna stops at the home flag, but it is
NOT pointed in-line with the Bow of the ship, it
is important to assure that the antennas actual
Figure 5-1 Antenna stops In-line with Bow
position (relative to the bow of the ship) is the
value that gets “preset” into the Relative
position counter. By saving the antennas actual Relative position when at the home flag into HFO, you
have calibrated the antenna to the ship.
5.3.1. To Calculate HFO:
If Targeting has been optimized by entering a large value of AZ TRIM; First, verify that you are
able to repeatably accurately target a desired satellite (within +/- 1.0 degrees). Then you can use
the AZ TRIM value to calculate the value of HFO you should use (so you can set AZ TRIM to
zero). AZ Trim is entered as the number of tenths of degrees. You will have to convert the AZ
TRIM value to the nearest whole degree (round up or down as needed). Calculated HFO value
is also rounded to the nearest whole number.
If AZ TRIM was a plus value: HFO = (TRIM / 360) x 255 Example: AZ TRIM was 0200
(plus 20 degrees). HFO = (20/360) x 255 = (0.0556) x 255 = 14.16 round off to 14.
If AZ TRIM was a negative value: HFO = ((360-TRIM) / 360)) x 255 Example: AZ TRIM
= -0450 (minus 45 degrees). HFO = ((360 – 45) / 360)) x 255 = (315 / 360) x 255 = 0.875

If Targeting has NOT been optimized, allow the antenna to initialize to its home flag position.

the antennas position relative to the Bow. If it appears to be very close to being parallel to the
bow, HFO will probably not be needed and you can proceed with Optimizing Targeting. If it is
NOT close, initialization was driving the azimuth CW, note if the antenna appears to have
stopped before it got to the Bow or if it went past the Bow. You may be able to guess an
approximate amount of how many degrees the antenna is from the bow. This is only intended
to help you initially find the satellite (which direction you will have to drive and approximately
how far you will have to drive). Refer, in general terms, to the Optimizing Targeting procedure.
If the antenna stopped before it got to the bow-line; When you initially target a satellite,
the antenna will also stop prior to the satellite position, so you that will have to drive the
Azimuth of the antenna UP to
actually find the satellite. Using
the same basic procedure as in
the Optimizing Targeting
paragraph, target the satellite
and record the “Calculated”
Azimuth position that the
antenna was driven to. Drive UP
until you find the satellite,
positively identify that you are on
the satellite you targeted and
allow tracking to peak the
antenna position. Record the
“Peak” Azimuth position.
Subtract the “Peak” position
from the “Calculated” position to
determine the number of
degrees of AZ TRIM that would

be required.
Example: In this new installation, I target my desired satellite and record the Calculated
Azimuth to be 180.5. I drive UP and finally find my desired satellite at a Peak Azimuth of
227.0 degrees. I subtract Peak from Calculated and difference to be –46.5 degrees,
therefore the actual Relative position that needs to be preset into the counter when the
antenna is at the Home Flag is 313.5. HFO = ((360-46.5) / 360)) x 255 = (313.5 / 360) x
255 = 0.87 x 255 = 222.06 which I round down to 222.
If the antenna went past the bow-line; When you initially target a satellite, the antenna
will also go past the satellite
position, so that you will have
to drive the Azimuth of the
antenna DOWN to actually
find the satellite. Using the
same basic procedure as in
the Optimizing Targeting
paragraph, target the satellite
and record the “Calculated”
Azimuth position that the
antenna was driven to. Drive
DOWN until you find the
satellite, positively identify
that you are on the satellite

Azimuth position. Subtract the “Peak” position from the “Calculated” position to
determine the number of degrees of AZ TRIM that would be required. . Refer to the
calculations above to determine the HFO you should use for this antenna.
Example: In this new installation, I target my desired satellite and record the Calculated
Azimuth to be 180.0. I drive DOWN and finally find my desired satellite at a Peak
Azimuth of 90.0 degrees. I subtract Peak from Calculated and difference to be +90.0
degrees, therefore the actual Relative position that needs to be preset into the counter
when the antenna is at the Home Flag is 90.0. HFO = ((90.0) / 360)) x 255 = 0.25 x 255
= 63.75 which I round up to 64.
5.3.2. To Enter the HFO value:
To enter the calculated HFO value, press & hold both LEFT and RIGHT arrows for six seconds to
enter the parameter menu at the EL TRIM parameter window. Press DOWN arrow key
numerous times (about 21) until you have selected the REMOTE COMMAND window.
In the REMOTE COMMAND window, press the LEFT arrow key until you have underscored the
left most character in the displayed value (ie the A in "A0000"). Use the UP/DOWN arrow keys to
increment/decrement the underscored character until it is upper case N (“N0000” should appear
in the command window). Press the RIGHT arrow key to move the cursor under the most
significant digit, then use the UP arrow key to increment it to a value of 6 (the display is now
“N6000”). Set the three digits to the right of the 6 to the three digit HFO value from 000 to 255
(corresponding to 0 to 360 degrees) that you calculated above. Use the LEFT/RIGHT keys to
underscore the desired digit(s) then use the UP/DONW arrow keys to increment/decrement the
underscored value. When you have finished editing the display value, press ENTER to send the
HFO value command to the PCU (but it is not save yet).
If you want to find out what the current HFO value is key in N6999 and hit ENTER.
When completed, you must save the desired HFO value. Press ENTER several times to select
the REMOTE PARAMETERS display. Press the LEFT or RIGHT arrow key to enter writing mode
and then press the ENTER to save the HFO value in the PCUs NVRAM.
EXAMPLE: In the “Antenna stopped before the Bow” example above, the HFO calculated was
222. To enter this value:
1. Set the Remote Command value to "N6222".
2. Press ENTER to send this HFO to the PCU. The display should now show "N0222".
3. When completed, you must save the desired HFO value. Press ENTER several times to
select the REMOTE PARAMETERS display. Press the LEFT or RIGHT arrow key to
enter writing mode and then press the ENTER to save the HFO value in the PCUs
NVRAM.
You have to drive the antenna CW in azimuth until the home switch is actuated, or re-initialize
the antenna to begin using the new HFO value you have entered and saved. To re-initialize the
antenna from the REMOTE COMMAND window of the ACU;
4. Press UP arrow key several times to return to the REMOTE COMMAND display.
5. Press the LEFT or RIGHT arrow key to enter edit mode. Use the LEFT/RIGHT and
UP/DOWN arrow keys to set the character and digits to "^0090" and then press the
ENTER key.
This resets the PCU on the antenna. The antenna will reinitialize with this command (Performs a
similar function as a power reset of the antenna) and the new home flag offset value will be
used to calibrate the Relative position of the antenna.

7.2.5. Test Tracking
Refer to the four quadrant Tracking check procedure in the Functional Testing section of this
manual.
7.2.6. Visual Inspection - Radome & Pedestal
Conduct a good, thorough, visual inspection of the radome and antenna pedestal. Visually
inspect the inside surface of the radome top and of the antenna pedestal. Look for water or
condensation, rust or corrosion, white fiberglass powder residue, loose wiring connections,
loose hardware, loose or broken belts or any other signs of wear or damage.
1. Radome Inspection - All the radome flanges are properly sealed to prevent wind,
saltwater spray and rain from being able to enter the radome. Re-seal any open
(“leaky”) areas with marine approved silicone sealant. If heavy condensation, or
standing water, is found inside the radome, isolate and seal the leak, and then dry out
the radome. Small (1/8 inch) holes may be drilled in the base pan of the radome to allow
standing water to “weep” out.
2. Antenna Pedestal Inspection - The shock/vibration springs and/or wire rope Isolators
should not be frayed, completely compressed, or otherwise damaged. The plated and
painted parts should not be rusted or corroded. The harnesses should not be frayed and
all the connectors should be properly fastened and tightened. All hardware should be
tight (no loose assemblies or counter-weights). Replace, re-coat, repair and/or tighten as
necessary.
7.2.7. Mechanical Checks
Turn the pedestal power supply OFF
1. Inspect inside of radome for signs that the dish or feed have been rubbing against the
inside of the fiberglass radome.
2. Rotate the pedestal through its full range of azimuth motion. The antenna should rotate
freely and easily with light finger pressure.
7-2

Maintenance and Troubleshooting
3. Rotate the pedestal through full range of elevation rotation. The antenna should rotate
freely and easily with light finger pressure.
4. Rotate the pedestal through full range of cross-level rotation. The antenna should rotate
freely and easily with light finger pressure.
5. Rotate the level cage through the full 90 degrees of rotation from CCW stop to CW stop.
The level cage antenna should rotate freely and easily with light finger pressure.
Attached cables should not cause the cage to spring back more that a few degrees from
either stop when released.
6. Inspect all drive belts for wear (black dust on/under the area of the belt).
7. Inspect AZ Drive chain. IF chain is beginning to show signs of rust or corrosion, apply a
light coat of light duty oil to the chain. Wipe excess oil off to leave a light coating on the
chain. DO NOT over-lubricate.
7.2.8. Check Balance
Check the balance of the antenna, re-balance as needed (refer to the Balancing the Antenna
procedure below).
7.2.9. Observe Antenna Initialization
Observe the Antenna Initialization as described in the Troubleshooting section below.
7.3.
Troubleshooting
7.3.1. Theory Of Stabilization Operation
The antenna system is mounted on a three axis stabilization assembly that provides free motion
with 3 degrees of freedom. This assembly allows the inertia of the antenna system to hold the
antenna pointed motionless in inertial space while the ship rolls, pitches and yaws beneath the
assembly. Three low friction torque motors attached to each of the three free axes of the
assembly provide the required force to overcome the disturbing torque imposed on the antenna
system by cable restraints, bearing friction and small air currents within the radome. These
motors are also used to re-position the antenna in azimuth and elevation.
The Pedestal Control Unit (PCU) uses inputs from the level cage sensors to calculate the amount
of torque required in each axis to keep the antenna pointed within +/-0.2 degrees. The basic
control loops for Cross Level, Level and Azimuth are shown in the Control Loop Diagram,
drawing 116287. The primary sensor input for each loop is the rate sensor mounted in the Level
Cage Assembly. This sensor reports all motion of the antenna to the PCU. The PCU
immediately responds by applying a torque in the opposite direction to the disturbance to bring
the antenna back to its desired position. Both the instantaneous output of the rate sensor
(Velocity Error) and the integrated output of the rate sensor (Position Error) are used to achieve
the high pointing accuracy specification.
The calculated torque commands are converted to a 5 volt differential analog signal by a Digital
to Analog converter (D/A) and sent to each of three Brush-Less Servo Amplifiers. These
amplifiers provide the proper drive polarities and commutation required to operate the BrushLess DC Servo Motors in torque mode. The Torque acting on the mass of the antenna cause it
to move, restoring the rate sensors to their original position, and closing the control loop.
Since the rate sensors only monitor motion and not absolute position, a second input is required
in each axis as a long term reference to keep the antenna from slowly drifting in position. The
Level and Cross Level reference is provided by a two axis tilt sensor in the level cage assembly.
The Azimuth reference is provided by combining the ships gyro compass input and the antenna
relative position.

Maintenance and Troubleshooting
14600-75 C-Band TXRX
7.3.2. Antenna Initialization (Series 97B & Series 00 )
Turn the pedestal power supply ON. The PCU will initialize the stabilized portion of the mass to
be level with the horizon and at a prescribed Azimuth and Elevation angles. The antenna will go
through the specific sequence of steps (listed below) to initialize the level cage, elevation, crosslevel and azimuth to predetermined starting positions.
Initialization is completed in the following phases, each phase must complete properly for the
antenna to operate properly (post-initialization). Observe the Initialization of the antenna
pedestal.
Step 1. The brakes on the Elevation and Cross-Level motors release.
Step 2. The level platform motor drives the Level Cage CW, issuing extra steps to
assure that the cage is all the way to the mechanical stop. Then the Level Cage will be
driven exactly 45.0 degrees CCW.
Step 3. Elevation axis then activates - Input from the LV axis of the tilt sensor is used to
drive the Elevation of the equipment frame to bring the tilt sensor LV axis to level. This
step takes approximately 10 seconds and will result in the dish being at 45.0 degrees in
elevation. The level cage may still be tilted left or right at this time.
Step 4. Cross-Level axis activates - Input from the CL axis of the tilt sensor is used to
drive Cross-Level of the equipment frame to bring the cross-level axis of the tilt sensor
to level (this results in the tilt of the Cross-Level Beam being level). This step takes
approximately 10 seconds.
Step 5. Azimuth axis activates - Antenna drives CW in azimuth until the “Home Flag”
signal is produced. This signal is produced by a Home Switch hitting a cam (or by a Hall
Effect sensor in close proximity to a Magnet). After another 10 second wait, the
antenna will report its version number at the Antenna Control Unit (ACU).
This completes the phases of initialization. At this time the antenna elevation should 45.0
degrees and Relative azimuth should be at home flag (home switch engaged on the home flag
cam).
If any of these steps fail, or the ACU reports model "xx97", re-configure the PCU as described in
the this chapter. If initialization still fails, this indicates a drive or sensor problem, refer to the
Troubleshooting section.
7.3.3. Antenna Loop Error Monitoring
The DacRemP DISPIVC graph chart provides a means for monitoring the accumulated velocity
errors of the antenna for diagnostic purposes. If this error is excessive, it indicates external
forces are acting on the antenna. These forces may be the result of but not restricted to static
imbalance, excessive bearing friction, cable binding, or wind loading. If these forces cause the
antenna to mis-point by more than 0.5° from the desired position the PCU will flag a “Stab
Limit” error.

Sensor and the Home Switch sensor for diagnostic purposes. The Tilt sensor (located inside the
Level Cage Assembly) is the primary input for the antenna’s reference to the horizon (0°

be ± 4 divisions from the red reference line. Any trace line average plotted above this is
of concern and troubleshooting required. See below for a screen capture of an antenna
that is Level in both the Cross-Level and Elevation Axis.
•
The Cross Level Tilt display should plot on the red reference line when the level cage is

This chart displays sensed output from the 3 rate sensors via three traces, CL (Cross
Level), LV (Elevation), and AZ (Azimuth), at a fixed 1º/Second/vertical division.

A normal trace display will be ± 1 divisions from the red reference line. The example
shown below shows an antenna that is NOT currently sensing motion in any axis.
•
The Cross Level display should decrease (plots below red line) as the antenna is tilted to
the left and increase (plots above red line) as the antenna tilted to the right.
•
The Level display should decrease (plots below red line) as the antenna is tilted forward
and increase (plots above red line) as the antenna is tilted back.
•
The Azimuth display should decrease (plots below red line) as the antenna is rotated
CCW and increase (plots above red line) as the antenna is rotated CW. In the example
below, the output of the Azimuth rate sensor is plotted above the reference line,
indicating that the antenna was driven CW in Azimuth. Due to the in-practicality of
driving an axis at a consistent rate, verification of rate sensor output is, for the most part
restricted to a positive or negative response of the Level Cage movement (plotting
above or below the red reference line of each axis).

7.3.7. To Disable/Enable DishScan
To be able to use Step Track, or to revert to Conscan, as your active tracking mode you will have
to disable DishScan.
Select the DISHSCAN parameter window on the ACU:
4. Press the RIGHT arrow, then press the UP arrow and last press the ENTER key to turn
DishScan mode ON.
5. Press the RIGHT arrow, then press the DOWN arrow and last press the ENTER key to
turn DishScan Mode OFF.
If you change this remote parameter, you must save the change using REMOTE PARAMETERS.
If DishScan is OFF and the Step Integral parameter is set to 0000, you will get a constant
ERROR 0016 (DishScan error) and you will see zeros flashing in the lower left of the Azimuth
and Elevation ENTRY menu displays. This is a visual indication that DishScan is turned OFF.
7.3.8. Satellite Reference Mode
The ships gyro compass input to the ACU may be accurate and stable in static conditions and
yet may NOT be accurate or stable enough in some underway dynamic conditions. If there is no
gyro compass or if the input is corrupt, not stable or not consistently accurate the tracking errors
will become large enough to cause the antenna to be mis-pointed off satellite.
Satellite Reference Mode will uncouple the gyro reference from the azimuth rate sensor control
loop. This decoupling of the Gyro source only happens 5 minutes after an azimuth command
has been sent to the antenna by means of an AZ target command, a search pattern initiated, or
the a Satellites longitudinal position is targeted. When operating in Satellite Reference Mode
changes in ships gyro reading will reflect its changes to the ACU’s display but will not directly
affect the azimuth control loop. The Pedestal Control Unit will stabilize the antenna based
entirely on the azimuth rate sensor loop and the tracking information from DishScan. This will
keep the azimuth rate sensor position from eventually drifting away at a rate faster than the
tracking loop can correct by using the tracking errors to regulate the rate sensor bias.

Maintenance
7.4.1. Balancing the Antenna
The antenna and equipment frame are balanced at the factory however, after disassembly for
shipping or maintenance, balance adjustment may be necessary. The elevation and cross-level
motors have a brake mechanism built into them, therefore, power must be ON to release the
brakes and antenna drive must be OFF to balance the antenna. . Do NOT remove any of the
drive belts. Balancing is accomplished by adding or removing balance trim weights at strategic
locations to keep the antenna from falling forward/backward or side to side. The antenna
system is not pendulous so 'balanced' is defined as the antenna remaining at rest when left in
any position. The antenna should be balanced within one ounce at the typical trim weight
location of 10 inches from the axis of rotation.
1. Turn Antenna power breaker ON
2. To turn OFF antenna drive (AZ, EL & CL) follow the procedure in paragraph 7.5 to set the
PCU configuration to “xx06” (N0000) but do NOT save.
3. Balance the antenna elevation axis with the elevation near horizon (referred to as front to
back balance) by adding, or subtracting, small counter-weights.
4. Then balance Cross Level axis (referred to as left-right balance) by moving existing
counter-weights. Do NOT add counter-weight during this step.
5. Last, balance the Elevation Axis with the antenna pointed at zenith (referred to as top to
bottom balance) by moving existing counter-weights. Do NOT add counter-weight
during this step.
6. When completed, the antenna will stay at any position it is pointed in for at least 5
minutes (with little, to no, ship motion).
7. Turn antenna power OFF, and then back ON, to re-Initialize the antenna. This will also
turn antenna drive (AZ, EL & CL) back ON.

7.4.2. To Adjust Tilt:
A REMOTE TILT calibration is required to align the level cage assembly correctly so that all
sensors will be aligned accurately to the axis they relate to. The fluid filled tilt sensor provides a
two dimensional horizon reference. The system is not able to automatically calculate the exact
center value, therefore it is necessary to perform this procedure to manually enter any offset
required to make sure the PCU receives a true reference to the horizon. The procedures below
describes the process of performing this calibration from either the ACU front panel or DacRemP
diagnostic software by connecting the ACU’s RS-422 M&C Port to an available serial port on a
Laptop/Desktop computer using a standard 9 pin serial cable.
Step 1 Turn Off DishScan Drive.
Using the DAC2202 ACU Front Panel:
1. Go to Remote Command window by pressing and holding the two LEFT &
RIGHT arrows
until the EL TRIM parameter is displayed.
2. Press and release both Left & Right arrow keys again. The “SAVE NEW

“RIGHT arrow to activate selection, then press the
Up arrow
to toggle state to OFF. Press the
ENTER key (Note: You will see that an
error code 16 is generated when DishScan movement is off.)
Using DacRemP:
1. Click on the
icon in the Comm Diagnostics window. (Verify that
DishScan is turned off by clicking the Error LED on main display panel, there
should be a check mark next to Conscan/DishScan)
(Steps 2-7 will require assistance to observe and operate antenna simultaneously)
Step 2: At Antenna, If not already installed, place a circular level bubble on top lid of level
cage.
Step 3: On the ACU front Panel, press either the
ENTER key or the
arrow key until the REMOTE TILT window is displayed
Step 4: Push the
DOWN
RIGHT arrow key to activate the Remote Tilt Mode.
Step 5: Based on the feedback from the technician observing the circular bubble, the
technician which operating the ACU will need to use the arrow keys to rotate the stabilized
antenna mass from front to back and left to right. You should wait at least 10 seconds
between commands to allow time for sensor to settle.
Left arrow will rotate antenna mass down to the left in the Cross-Level axis ½ degree
Right arrow will rotate antenna mass up to the right in the Cross-Level axis ½ degree
Up arrow will rotate antenna mass up in the Level axis ½ degree
Down arrow will rotate antenna mass down in the Level axis ½ degree

Antenna Stowing Procedure
WARNING: Antenna Pedestal must be properly restrained (stowed)
to prevent damage to wire rope isolators, isolator springs and/or
antenna pedestal mechanism during underway conditions when power
is removed from the antenna assembly.
The normal operating condition for the Sea Tel Antenna system is to remain powered up at all times.
This ensures that the antenna remains actively stabilized to prevent physical damage to the antenna
pedestal and reduce condensation and moisture in the radome to prevent corrosion. If, for some reason,
the antenna must be powered down during underway transits, it should be secured with nylon straps
regardless of sea conditions to prevent damage to the antenna system. Refer to the procedure below to
secure the antenna pedestal.
Equipment & Hardware needed:
•
Two (2) ½-13 x 2-inch Stainless Steel bolts.
•
Two (2) Nylon straps with ratchet mechanism. Nylon straps must be rated to 300 lbs.
Working load capacity and 900 lbs. Max rated capacity.
Stowing procedure:
7-18
14600-75 C-Band TXRX
Maintenance and Troubleshooting
1. Point the antenna to Zenith, (90 degree elevation
angle), straight up.
2. Install one (1) ½-13 x 2-inch bolt into the inside of
each elevation beam as shown in Figure 1.
3. Hook one end hook of the nylon strap to bolt in
elevation beam as shown in Figure 2.
4. Hook the other end hook of the nylon strap to the
pedestal-mounting frame as shown in Figure 3.
7-19
Maintenance and Troubleshooting
14600-75 C-Band TXRX
5. Use the ratchet of the strap to tighten nylon straps.
As the straps are tightened, observe the vertical
isolation canister assembly as shown in Figure 4.
6. Tighten straps until the canister has been pulled
down approx. ¼ to ½ inch. Do not over-tighten. You
must leave approximately 1/8 inch clearance
between the rubber stops and the azimuth driven
sprocket to allow the vertical vibration isolation to
function properly.
NOTE: Remove both the straps and the bolts before applying power and returning the
antenna to normal operating condition.

FEATURES
125W Ku-Band 1:1 Phase Combined SSPB System with FPRC-1100 Controller
and RCP2-1100 Controller for L-Band redundancy
DESCRIPTION
Paradise Datacom’s family of outdoor packaged, phase
combined solid state power amplifier (SSPA) systems provide
the highest degree of redundancy and system reliability.
Phase Combined amplifier systems can be configured using
Paradise Datacom’s High Power Outdoor amplifiers.
1:1 Phase Combined Systems are an economical solution to
providing high output power capability with soft-fail redundancy.
1:2 Phase Combined Systems can provide full output power
redundancy to mission critical applications which cannot
tolerate any decrease in output power capability.
Both 1:1 and 1:2 Phase Combined Systems utilize a signal box
through which all RF and L-band input signals are distributed.
This ensures that any reference signal is modulated to each
amplifier at the same frequency, and that the phase adjustment
is optimized.

1:1 Phase Combined / Redundant System
The 1:1 Fixed Phase Combined Redundant System is a popular system architecture that
enables two Solid State Power Amplifiers to operate as a normal 1:1 redundant system or a
phase combined system. The basic system topology is very similar to a 1:1 redundant system
and is shown in the block diagram. An additional switch is included which allows either
amplifier to be individually connected to the antenna or connect both amplifiers to a
waveguide combiner.

1:1 Phase Combined System Simplified Block Diagram
1:2 Phase Combined / Redundant System
The 1:2 Phase Combined Redundant System is a system architecture that enables Solid
State Power Amplifiers to achieve higher output power levels while building in a level of
redundancy. The basic system topology is similar to a 1:2 redundant system shown in the
block diagram below. Amplifiers #1 and #3 are normally online. The outputs of #1 and #3 are
directed by the waveguide switches into a low loss power combiner. In the event of a failure
of either on line amplifier, the standby amplifier, #2, can be switched in place of either #1 or
#3 and the system maintains full output power.

System Output Power Capacity
Due to the output waveguide and switches, there is always some residual loss in the output of
phase combined HPA systems. This results in slightly less than the ideal 3dB power addition
to the output power of a single HPA unit.
On 1:1 phase combined systems, the typical additive output power is 2.70 dB above the
output power of a single HPA. On 1:2 phase combined systems, the typical additive output
power is 2.50 dB above the output power of a single HPA.
For example, a 125W Ku-Band Compact Outdoor SSPA in a 1:1 phase combined system
would have the following output power:
Single HPA: P1dB = 50.0 dBm; Psat = 51.0 dBm
1:1 phase combined system: P1dB = 52.7 dBm; Psat = 53.7 dBm

L-Band Operation
Paradise Datacom Phase Combined HPA Systems can be configured for L-Band Input
operation. For optimum RF phase combining over the entire bandwidth of a communication
amplifier, the frequency translation part of the system must be separated from the phase
combining loop. Therefore, systems with L-Band input are configured with a separate
1:1 system of L-Band Block Up Converters that feed the 1:1 or 1:2 Phase Combined HPA
system. If L-Band redundancy is not required, the system can be configured with a single
thread L-Band Block Up Converter.

The Block Up Converter system is housed in a weather-proof enclosure (shown below) and
controlled by an indoor RCP2-1100 Redundant Controller. The Up Converters can be
configured with internal reference oscillators or external reference oscillators. The Paradise
Datacom ZBUC architecture allows a converter that is fitted with an internal reference
oscillator to automatically detect and switch to an externally applied 10 MHz reference signal.

FPRC-1100 1:1 Phase Combined System Controller
FPRC-1200 1:2 Phase Combined System Controller
The FPRC-1X00 is the heart of the Redundant SSPA System. It provides an extremely user
friendly interface for complete monitor and control of the high power amplifiers. The front
panel mimic display shows the on-line amplifiers and the switch positions. Fault lights are
provided for easy indication of system status.
All FPRC-1X00 monitor and control is available locally at the front panel LCD display, as well
as remotely by the RS232 , RS485, or Ethernet interface ports. Audible alarms and a full compliment of parallel I/O signal are available at the rear panel of the FPRC-1X00.
The FPRC-1X00 System Controller allows the Phase Combined System of amplifiers to be
controlled as if it were a single SSPA. The FPRC is the single point of interface for either
local, front panel, or remote control. System monitor and control capability include gain
adjustment, output power monitoring (dBm or Watts), and alarms.
The FPRC-1X00 is a 1RU indoor control unit that contains its own internal redundant
components including fully redundant power supplies.
Note: Systems can be configured without the use of a system controller. Consult the factory for operation of phase combined systems without
a system controller.
