Introduction
Introduction
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 Television Receive Only (TVRO) system provides you with satellite TV programming while inport or
underway. Your Antenna system will receive signals of adequately high E.I.R.P. levels (see the Specifications section of
this manual), in linear or circular polarization mode from any of the geosynchronous TV satellites at C-Band or Ku-band
frequencies (dependant upon currently installed feed assembly). This input will be distributed to all of your satellite TV
receivers which will provide the Audio/Video to your Televisions. Many satellites also provide CD quality audio
programming which may also be routed to your stereo equipment.
1.3.
System Components
Your TVRO Antenna 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.
Video and Audio outputs from your satellite receivers are available for distribution and monitoring.
For more information about these components, refer to the Basic System Information section of this manual.

Operation
Operation
2.1.
System Power-up
Turn the Power switch on the louvered panel of the antenna pedestal ON. This will energize the antenna pedestal and
the associated RF equipment.
Turn the Antenna Control Unit (ACU) Power switch ON.
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 CrossLevel 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).
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. Auto-Polarization mode is the default polarization mode of operation from the ACU. Polarization may
2-1
Operation
14400MK2-21 C/Ku-Band TVRO
be operated manually from the ACU for diagnostic or alignment purposes. Refer to the Antenna Control Unit manual
for more operation information.
2.7.
Low Noise Block Converter Operation
There are no operating instructions or controls applicable to the LNB. This unit is energized whenever the matrix
switch and satellite receiver(s) have AC power connected to them.
Satellite signals are either circular polarized (spiraling plane down from the satellite) or linear polarized (fixed plane
down from the satellite). The pedestal will receive circular polarization signals when a circular LNB is installed on the
back of the dish. Conversely, the pedestal will only receive linear polarized signals when a linear LNB is installed.
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.

Installation
3.2.
14400MK2-21 C/Ku-Band TVRO
Site Selection Aboard Ship
The radome assembly should be installed at a location aboard ship where:
•
The antenna has a clear line-of-sight to view as much of the sky (horizon to zenith at all bearings) as is
practical.
•
X-Band (3cm) Navigational Radars:
•
•
The ADE should be mounted more than 0.6 meters/2 feet from 2kW (24 km) radars
•
The ADE should be mounted more than 2 meters/8 feet from 10kW (72 km) radars
•
The ADE should be mounted more than 4 meters/12 feet from 160kW (250km) radars
S-Band (10cm) Navigational Radars:
•
If the ADE is/has C-Band it should be mounted more than 4 meters/12 feet from the S-band Radar.
•
The ADE should not be mounted on the same plane as the ship's Radar, so that it is not directly in the Radar
beam path.
•
The ADE should be mounted more than 2.5 meters/8 feet from any high power MF/HF antennas (<400W).
•
The ADE should be mounted more than 4 meters/12 feet from any high power MF/HF antennas (1000W).
•
The ADE should also be mounted more than 4 meters/12 feet from any short range (VHF/UHF) antennae.
•
The ADE should be mounted more than 2.5 meters/8 feet away from any L-band satellite antenna.
•
The ADE should be mounted more than 3 meters/10 feet away from any magnetic compass installations.
•
The ADE should be mounted more than 2.5 meters/8 feet away from any GPS receiver antennae.
•
Another consideration for any satellite antenna mounting is multi-path signals (reflection of the satellite
signal off of nearby surfaces arriving out of phase with the direct signal from the satellite) to the antenna.
This is particularly a problem for the onboard GPS, and/or the GPS based Satellite Compass.
•
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.
•
This mounting platform must also be robust enough to withstand the forces exerted by full rated wind load
on the radome.
•
The mounting location is robust enough that it will not flex or sway in ships motion and be sufficiently well
re-enforced to prevent flex and vibration forces from being exerted on the antenna and radome.
•
If the radome is to be mounted on a raised pedestal, it MUST have adequate size, wall thickness and gussets
to prevent flexing or swaying in ships motion. In simple terms it must be robust.
If these conditions cannot be entirely satisfied, the site selection will inevitably be a “best” compromise between the
various considerations.
3.3.
Preparing For The Installation
3.3.1. Unpack Shipping Crates
Exercise caution when unpacking the equipment.
3.3.2. Inspect / Inventory
Carefully inspect the radome panel surfaces for evidence of shipping damage. Inspect the pedestal assembly
and reflector for signs of shipping damage.
3.3.3. Prepare ADE Mounting Location
Prepare the mounting location for the Radome. If the radome is to be bolted to the deck (or a platform)
assure that the mounting holes have been drilled. Assure that the mounting hardware has been obtained and
is readily available.
3.3.4. Preparing BDE Location
Prepare the mounting location for the Below Decks Equipment. These equipments would normally be
installed in a standard 19” equipment rack. Refer to the Antenna Control Unit manual for installation of the
ACU and the Terminal Mounting Strip.
3-2
14400MK2-21 C/Ku-Band TVRO
Installation
Refer to the vendor supplied manuals for installation of the other below decks equipments.
Prepare other locations throughout ship for any other equipment which is not co-located with the ACU.
3.3.5. Installing The System Cables
Install appropriate cables from Below Decks Equipment to the ADE Location(s).
The cables must be routed from the above-decks equipment group through the deck and through various ship
spaces to the vicinity of the below-decks equipment group. When pulling the cables in place, avoid the use of
excessive force. Exercise caution during the cable installation to assure that the cables are not severely bent
(proper bend radius), kinked or twisted and that connectors are not damaged.
Assure that the cables have been run through watertight fittings and/or will not permit water entry into the
ship when the installation is completed. After cables have been routed and adjusted for correct cable length
at each end, seal the deck penetration glands and tie the cables securely in place.
3.4.
Assembling the ADE
The assembly procedure described below begins by sub-assembling sections of the baseframe, radome and pedestal.
Then these are assembled to form the ADE.
3.4.1. Preparing for Assembly of the ADE
Read this entire assembly procedure before beginning.
Refer to the System Block diagram, General Assembly, Baseframe Assembly, Radome Assembly and Radome
Installation Arrangement drawings for your system.
Select a secure assembly site that provides enough area to work with the large radome panels while subassembling the baseframe, sections of the radome, Antenna Pedestal and Reflector & Feed. The area should
be a clean, flat location, free of rocks & debris (ie concrete). The site should also provide protection from
wind, rain and other adverse weather. A hoist, or small crane, is needed to assemble these sub-assemblies to
form the final ADE Assembly.
As an example, you might sub-assemble everything on the pier where the ship will tie up, then use the crane
to put the sub-assemblies together and lift the whole ADE up to the mounting location on the ship.
You can change order of these steps, however, in the end the objective is to have a well sealed
radome with flanges that are clean of excess caulking. In addition it is important that the ADE is
structurally sound for severe weather conditions.
3.4.2. Sub-assemble the Base Frame Assembly
Refer to the Base Frame Assembly drawing for your system and the procedure below.
NOTE: Unless otherwise indicated, all nuts and bolts should be assembled
with Loctite 2760 or its equivalent.

on the base frame. Install the
mounting hardware in the
four pan mounting holes.
Align the base pan perimeter
holes to the mounting holes
in the base frame. Note: You
may want to temporarily
insert bolts in 8-12
equidistant holes around the
perimeter of the base pans to
provide good alignment
throughout the perimeter
hole pattern.
Apply Loctite to the mounting
hardware and tighten. If
alignment bolts were inserted
around the perimeter in the
previous step, remove them
now.

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.
4.1.
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.
4.2.
Optimizing Targeting (Auto Trim)
The following feature requires your antenna have GSR2 minimum software versions installed. First, assure that all of
your Ship & Satellite settings in the ACU are correct. Target and, if required manually locate the desired satellite.
Allow 1 to 2 minutes for the antenna to “peak” on the signal. Verify positive satellite identification, in a TVRO system
verify either Receive NID or that at least one Television is producing video, in a VSAT system verify receive lock
indication on the satellite modem.
Access the ACU Setup Mode Parameter “AUTO TRIM”, Press the UP arrow and then press Enter.
Drive the antenna completely off satellite (Target and Azimuth value of 0)
Retarget the satellite and verify the system peaks on satellite with positive satellite identification within 1 minute.
Access the ACU Setup Modes “SAVE NEW PARAMETERS”, Press the UP arrow and then press Enter
4.3.
Optimizing Targeting (Manually)
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.
4.4.
Radiation Hazard and Blockage Mapping (AZ LIMIT parameters)
This system may be programmed with relative azimuth and elevation sectors (zones) where blockage exists or where
transmit power would endanger personnel who are frequently in that area.
Refer to your ACU Manual for instructions on programming of these zones.

Blockage Simulation Test
Blockage output function is used to modify the behavior of Tracking and Searching when there is a known blockage
zone. The ACU provides a contact closure to ground on the SW2 terminal of the Terminal Mounting Strip when the
antenna is pointed within any one of the blockage/hazard zones or the system is searching, targeting, unwrapping or is
mis-pointed by 0.5 degrees or more (FCC TX Mute function for Transmit/Receive systems only). The contact closure
is a transistor switch with a current sinking capability of 0.5 Amp. This logic output control signal is used for:
•
When used as simple “BLOCKED” logic output for a single Sea Tel antenna, this output could be used to light a
remote LED and/or sound a buzzer to alert someone that the antenna is blocked, and signal is lost.
•
In a “Dual Antenna” installation, this logic output(s) is used to control Dual Antenna Arbitrator panel of coax
switches to switch the source inputs to the matrix switch from Antenna “A” to Antenna “B”, and vice versa.
•
When used as simple “RF Radiation Hazard” logic output for a single Sea Tel TX/RX antenna, this output
could be used to suppress RF transmissions while the antenna is pointed where people would be harmed by
the transmitted microwave RF power output. The SW2 output would be interfaced to the satellite modem to
disable the TX output signal from the Satellite TXRX Modem whenever the antenna is within the RF
Radiation Hazard zone(s).
•
When used for “FCC TX Mute” logic output for a single Sea Tel TX/RX antenna, this output could be used to
suppress RF transmissions whenever the antenna is mis-pointed 0.5 degrees or more, is blocked, searching,
targeting or unwrapping. The SW2 output would be interfaced to the satellite modem to disable/mute the
TX output signal from the Satellite TX/RX Modem. When the mute condition is due to antenna mis-pointing,
it will not un-mute until the pointing error of the antenna is within 0.2 degrees. The default output is
contact closure to ground when the antenna is mis-pointed, therefore provides a ground to “Mute” the
satellite modem on the SW2 terminal of the Terminal Mounting Strip. If your satellite modem requires an
open to “Mute”, refer to SYSTEM TYPE parameter 16 value to reverse the output logic from the ACU.
To Test the blockage function:
1. Press the NEXT key until you are at the Status menu. Press ENTER to access the Tracking menu.
2. Press the RIGHT arrow key to bring up and move the cursor to the far right. Press the UP arrow to simulate a
manual BLOCKED condition. BLOCKED will appear in the Tracking display.
3. Verify that SW2 terminal shorts to ground (or open circuit if you have SYSTEM TYPE configured to reverse
the output logic) and that the external alarms actuate OR the Dual Antenna Arbitrator coax switches toggle
(if antenna B is not blocked) OR the Satellite Modem TX is disabled/muted.
4. Press the LEFT arrow key and then press the UP arrow key to turn the simulated blocked condition OFF.
BLOCKED will disappear from the Tracking display.
5. Verify that SW2 terminal is open circuit (or ground if you have logic reversed) and that the external alarms
deactivate OR the Satellite Modem TX is un-muted. The Dual Antenna Arbitrator coax switches should not
toggle until you manually block Antenna B ACU.

6.2.5. Test Tracking
Refer to the four quadrant Tracking check procedure in the Functional Testing section of this manual.
6.2.6. 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.
6.2.7. 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.
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.
6.2.8. Check Balance
Check the balance of the antenna, re-balance as needed (refer to the Balancing the Antenna procedure
below).
6.2.9. Observe Antenna Initialization
Observe the Antenna Initialization as described in the Troubleshooting section below.

Maintenance and Troubleshooting
400MHz Modem Configuration
The 400MHz FSK modem PCB has a jumper block (located
component side of PCB) that is used to configure it for Above
Decks or Below Decks operation as well as to configure its’ serial
communications protocol (RS232, RS422, or RS485). Based on
the desired mode of operation, the appropriate jumper(s) will be
installed at the factory, prior to shipment of a completed system.
In general, no field modifications to these jumper settings are
required, except when it is required to re-configure a modem to
operate in a different mode of operation ( i.e. converting a spares
kit below decks modem to operate as an above decks modem or
re-configuring an ADE Modem for M&C integration with a newly
installed RF package change that requires RS485 communications
instead of RS422). Refer to the table below for the proper jumper
settings.

400 MHz LED indicators
For diagnostic purposes, the 400MHz FSK Modem Assemblies have an LED Indicator (located to the on the bottom left
hand side of the Enclosure for BDE modems and directly underneath the Rotary Joint port on the 09 Series PCU). By
observing the amount of amber colored flashes during power up, the modems configuration may be established. You
can also verify the communications link between above decks and below decks modems themselves. Refer to the
below list for an explanation of the different LED states.
•
Upon power up, the modems’ LED will flash amber. The number of flashes indicates the dash number
configuration of the modem. Refer to the configuration chart above for the appropriate dash configuration
for your modem assembly.
•
A flashing Red LED indicates no communication between modems (2 failed channels).
•
An LED alternating Red and Green indicates a single channel failure.
•
Solid green indicate dual channel communications lock between modems (i.e. there is enough signal being
received to establish communications).

400 MHz Modem Signals
6.5.1. Pedestal M&C
RS-422 Antenna Monitor and Control signals pass from the ACU’s J4 Antenna Port, through the PED M&C
port of the 400MHz base modem and are modulated and demodulated. The modulated signal(s) are then
diplexed with the RxIF signal. This modulated signal travels on the Rx IF cable, between the MUX Rack Panel
and then into 400 MHz pedestal modem. The Pedestal modem then converts the RF Signal back to RS-422,
before routing to the M&C port of the Pedestal Control Unit via an interface cable.

6.5.2. Radio M&C
The RS-232, RS-422, or RS-485 (depending on configuration) Radio M&C signals pass from the BDE computer
through the RF M&C port of the base modem and are modulated and demodulated. These M&C signals are
diplexed with the Pedestal M&C signals before passing through to the above decks modem. The Pedestal
modem then converts the RF Signal back to RS-232/422/485, before routing to the M&C port of the above
decks radio equipment via an interface cable.
6.5.3. Channel Identification
There are four base frequencies used in the 400MHz FSK modem assemblies:
•
The BDE Modem Transmits Pedestal M&C at 452.5 MHz
•
The BDE Modem Transmits Radio M&C at 447.5 MHz
•
The ADE Modem Transmits Pedestal M&C at 465.0 MHz
•
The ADE Modem Transmits Radio M&C at 460.0 MHz

Troubleshooting
6.7.1. 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 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 Brush-Less 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.
6.7.2. Series 97B-21/00B-21 Dual C-Band OR Quad Ku-Band TVRO RF Flow
Refer to the System Block Diagram in the Drawings section of this manual. The feed has a 24VDC motor to
rotate the body of the OMT to optimize the linear polarization angle of the LNBs to the polarization angle of
the signal coming from the targeted satellite. The 24VDC motor is remotely controlled by the ACU (Manual
OR Auto-Polarization) through the PCU and Shielded Polang Relay Assy.
Two fixed frequency C-Band LNBs and one Quad Ku-Band LNBs are installed. Both C-Band polarizations (H &
V) are routed to J1 of the coax switches mounted on a C/Ku Switch Panel. Both Ku-Low Band polarizations
(H&V) are routed to J2 of the coax switches. The coax switches are controlled from the ACU MODE –
TRACKING Band Selection through the PCU and the Shielded Polang Relay Assy. The ACU band selection will
route either the C-Band, OR the Ku-Low Band, signals through two of the channels of the rotary joint. The
other two channels of the coax rotary joint are the (un-switched) Ku-High Band outputs of the Quad Ku LNB.
6.7.2.1. Channel 1 (White)
HORIZ C/Ku-low coax has +18 VDC Voltage supplied by Matrix Switch plus C-Band IF (9501450MHz) OR Ku-Band IF (950-1950MHz) “Band Selected” output from the C/Ku-low Switch.
Horizontal C/Ku-low band switched output passes through this channel of the 75 ohm coaxial rotary
joint, to the base of the radome, down the ADE-BDE coax to the C/Ku HORIZ LO input of the four
port Matrix Switch. The ACUs’ Tracking Receiver and each of the C or Ku-Band Satellite Receivers is
connected by coax cable to one of the available IF outputs of the Matrix Switch. Total signal loss of
this path is the accumulation of the coax cable losses from antenna to receiver, plus the loss in the
C/Ku Switch and the Matrix Switch.
6.7.2.2. Channel 2 (Blue)
VERT C/Ku-low coax has +13 VDC Voltage supplied by Matrix Switch plus C-Band IF (950-1450MHz)
OR Ku-Band IF (950-1950MHz) “Band Selected” output from the C/Ku-low Switch AND Antenna
Control RF (Pedestal TX at 1.1 & Base TX at 1.5 MHz) which is added onto this coax by the Pedestal
FSK Modem (connected to the PCU). Vertical C/Ku-low band switched output passes through this
channel of the 75 ohm coaxial rotary joint, to the base of the radome, down the ADE-BDE coax to
the Base FSK Modem (connected to the ACU) and then to the C/Ku VERT LO input of the four port
Matrix Switch. Total signal loss of this path is the accumulation of the coax cable losses from
antenna to receiver, plus the loss in the C/Ku Switch, Pedestal & Base Modems (1 dB max loss each)
and the Matrix Switch.
6.7.2.3. Channel 3 (Red)
HORIZ Ku-high coax has +18 VDC Voltage supplied by Matrix Switch plus Ku-Band IF (11002150MHz). Horizontal Ku-high band un-switched output passes through this channel of the 75 ohm
coaxial rotary joint, to the base of the radome, down the ADE-BDE coax to the Ku HORIZ HI input of
the four port Matrix Switch. Total signal loss of this path is the accumulation of the coax cable
losses from antenna to receiver, plus the loss in the Matrix Switch.
6.7.2.4. Channel 4 (Green)
VERT Ku-high coax has +13 VDC Voltage supplied by Matrix Switch plus Ku-Band IF (11002150MHz). Vertical Ku-high band un-switched output passes through this channel of the 75 ohm
coaxial rotary joint, to the base of the radome, down the ADE-BDE coax to the Ku VERT HI input of
the four port Matrix Switch. Total signal loss of this path is the accumulation of the coax cable
losses from antenna to receiver, plus the loss in the Matrix Switch.

Antenna Initialization (Series 97B & Series 00 MK2)
Turn the pedestal power supply ON. The brakes on the Elevation and Cross-Level motors will release. A brake
release power supply control circuit supplies 24 VDC to the brakes initially (5-10 seconds) and then reduces
the voltage to 12VDC. The PCU will initialize the stabilized portion of the mass to be level with the horizon
and at a prescribed Azimuth and Elevation angles in the specific sequence of steps listed below.
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.
6-12
14400MK2-21 C/Ku-Band TVRO
Maintenance and Troubleshooting
Step 1. Elevation and Cross-Level axes activate simultaneously - Input from the Elevation sensor is
used to drive the Elevation of the equipment frame to 45.0 degrees in elevation. Input from the
Cross-Level sensor is used to drive Cross-Level of the equipment frame to bring it to level (this
results in the tilt of the Cross-Level Beam being level).
Step 2. Azimuth axis activates - Antenna drives CW in azimuth until the “Home Flag” signal is
produced. This signal is produced by a Proximity sensor in close proximity to a metal tab. After a
short period of time (a total of approximately 1-2 Minutes after power is initially applied to the
antenna), the PCU will report its model setting and software version number to 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 actuated).
If any of these steps fail, or the ACU reports model "xx97B or xxx00B", re-configure the PCU as described
in the Maintenance section of this manual. If initialization still fails, this indicates a drive or sensor problem.
6.7.4. Troubleshooting using DacRemP
While troubleshooting a Sea Tel 3-Axis Antenna System, you must classify the fault you are dealing with as a
failure within one of 3 major system functions, Targeting, Stabilization, and Tracking. Should there be a
failure with any one of these functions, your system will not operate properly. A few simple checks may help
determine which fault (if any) that you are dealing with. The matrix below lists some test(s) and which of the
DacRemP graph selection would be best to use to identify a fault. The end of this chapter contains examples
on how to use DacRemP to diagnose a fault.
Targeting: is the ability to accurately point the antenna to an angular position in free space and is
controlled by the ACU. (Does the system drive to the Azimuth, Elevation, and Polarity positions within 1
degree of the desired satellite?)
Stabilization: is the process of de-coupling the ships motion from the antenna and is controlled by the
PCU. (Does the system maintain the satellite link after turning off TRACKING?)
Tracking: is the process of issuing fine adjustments to the pointing angle of the antenna to optimize the
received signal level and is controlled by the ACU. (Does the system pass a four quadrant-tracking test?)

6.7.5. 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.

6.7.6. Reference Sensor Monitoring
The DacRemP DISPV graph chart provides a means for monitoring the output of the 2 Axis Tilt 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° Elevation and 90° Cross-Level). While the
Home Switch Sensor (located at the antenna base) is used to calibrate the antenna’s position relative to the
vessels BOW.

The Cross Level Tilt display should plot on the red reference line when the level cage is level,
referenced to the horizon. It should decrease (plots below red line) when the antenna is tilted to the
left and increase (plots above red line) when tilted to the right. See below for a screen capture of an
abnormal CL trace Plot, it is an indication that the antenna that is either listed to the right approx. 4
degrees or the PCU requires to much CL tilt bias.

driven so that the Home Flag switch is engaged.
6.7.7. Open Loop Rate Sensor Monitoring
The DacRemP DISPW graph chart provides a means for monitoring the output of the 3 solid state rate
sensors (located inside the Level Cage Assembly) for diagnostic purposes. The rate sensors are the primary
inputs to the PCU for stabilization.

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).
6.7.8. Open Loop Motor Test
The DacRemP Comm Diagnostics Window provides a means to
enter in Remote Commands for driving each individual torque
motor to test that motors functionality. By driving each axis and
observing the resulting motion of the antenna, a coarse
operational status of the motor and motor driver may be
established.

6.7.9. To Disable/Enable DishScan®
Tracking optimizes the pointing of the antenna, in very fine step increments, to maximize the level of the
satellite signal being received. DishScan® is the default mode of tracking.
To toggle the ON/OFF state of DishScan®, select the remote parameter DISHSCAN. This remote parameter
allows you to view, or change, the DishScan® ON/OFF status.
1. Press UP arrow and ENTER to turn DishScan® ON.
2. Press DOWN arrow and ENTER to turn DishScan® OFF.
3. 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.
When DishScan® is turned OFF, the system will NOT be able to properly track any satellite.
6.7.10.
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. When
operating in Satellite Reference Mode changes in ships gyro reading 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.
Satellite Reference Mode can be used as a diagnostic mode to determine if tracking errors are caused by
faulty gyro inputs.
It should normally be OFF as long as you have an accurate, reliable, gyro compass input available.
It MUST be OFF when the elevation angle is greater than 75 degrees. Above 75 degrees Elevation, the
ability of Sat Reference tracking to correct the Az Rate sensor bias begins to degrade, especially on a circular
C system.
Satellite Reference Mode MUST be ON when:
•
No Gyro Compass is available.
•
The Gyro Compass input is noisy, occasionally inaccurate or occasionally unavailable.
•
Frequent or constant ACU Error Code 0001 (Gyro Compass has failed).
• Using an uncompensated Flux Gate Compass.
To view, or change, the Satellite Reference Mode status, select the SAT REF remote parameter:
4. Press the UP arrow and then press the ENTER key to turn Satellite Reference Mode ON.

Maintenance
6.8.1. 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 DishScan® 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 “REMOTE BALANCE” parameter (located at the end of the Remote Parameters after REMOTE TILT) of the
ACU. When enabled, Remote Balance Mode temporarily turns DishScan®, Azimuth, Elevation and CrossLevel drive OFF. This function is required when trying to balance antenna systems that have a built-in brakes
on the elevation and cross-level motors.
Assure that Antenna power is ON and that the antenna has completed initialization.
At the ACU:
1. From the ACU - REMOTE BALANCE parameter: Enable balance mode (refer to your ACU manual).
The screen should now display “REMOTE BALANCE ON”.
At the Antenna:
2. At the Antenna: Balance the antenna with the elevation near horizon (referred to as front to back
balance) by adding, or subtracting, small counter-weights.
3. Then balance Cross Level axis (referred to as left-right balance) by moving existing counterweights from the left to the right or from the right to the left. Always move weight from

Maintenance and Troubleshooting
one location on the equipment frame to the same location on the opposite side of the equipment
frame (ie from the top left of the reflector mounting frame to the top right of the reflector
mounting frame). Do NOT add counter-weight during this step.
Last, balance the antenna with the elevation pointed at, or near, zenith (referred to as top to bottom
balance) by moving existing counter-weights from the top to the bottom or from the
bottom to the top. Always move weight from one location on the equipment frame to the same
location on the opposite side of the equipment frame (ie from the top left of the reflector
mounting frame to the bottom left of the reflector mounting frame). Do NOT add counter-weight
during this step.
When completed, the antenna will stay at any position it is pointed in for at least 5 minutes (with no
ship motion).
Do NOT cycle antenna power to re-Initialize the antenna. Return to the ACU, which is still in
REMOTE BALANCE mode, and press ENTER to exit Remote Balance Mode. When you exit Balance
Mode the antenna will be re-initialized, which turns DishScan®, Azimuth, Elevation and Cross-Level
drive ON.
6.8.2. 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.

Maintenance and Troubleshooting
Pedestal Control Unit Configuration (xx97B & xx00 MK2)
The PCU is designed to be used with a variety of antenna pedestal configurations. The configuration information that
is unique to each pedestal type is stored in a Non Volatile Random Access Memory (NVRAM) in the PCU enclosure. If
the PCU is replaced or the NVRAM in the PCU should become corrupt, the PCU must be re-configured to operate with
the pedestal it is installed on. The default configuration for the PCU is model xx97B. In this configuration the PCU will
not drive any of the three torque motors to prevent damage to the unknown pedestal.

6.10. 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:
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.
6-26
14400MK2-21 C/Ku-Band TVRO
Maintenance and Troubleshooting
4. Hook the other end hook of the nylon strap to the pedestalmounting frame as shown in Figure 3.
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.
