If you work on a roof, tower, or other high structure, or use a ladder or
scaffold to access the work site, follow these precautions to prevent personal
injury or death:





Walk only on sound roof structures.
Make sure the antenna assembly and installation surface are
structurally sound so that they can support all loads (equipment weight,
ice, and wind).
Use safety equipment (e.g., a lifeline) appropriate for the work location.
Follow all manufacturer safety precautions for all safety and other
equipment used.
Perform as many procedures as possible on the ground.
 To avoid electric shock, stay at least 20 ft away from power lines when
there is a chance that you or the equipment you are using could
accidentally come into contact with the power lines. Always look up and
check for overhead lines before moving a ladder.
 If any part of the antenna or mount assembly comes in contact with a
power line, call the local power company to remove it. Do not try to
remove it yourself. If the antenna reflector contacts electric power lines,
you could be killed or seriously injured.
 For pole mount installations, be sure to obtain information regarding
underground utilities in the proposed location before digging.
 Call local utility companies before digging to avoid striking underground
cables, pipes, or electric lines.
 Striking or cutting underground cables, pipes, or electric lines can cause
personal injury or property damage.
Properly ground the antenna assembly in accordance with all local and
national electrical codes.
If the antenna or mount assembly begins to fall during the installation, do not
attempt to catch it. Move away and let it fall.

Antennas that have been improperly installed or attached to an unstable
structure are susceptible to wind damage, which can be very serious or even
life threatening. The product owner and installer assume full responsibility
that the installation is structurally sound to support all loads (weight, wind,
and ice) and is properly sealed against leaks.
Observe these precautions to avoid exposure to RF radiation, a potential
safety hazard:








The antenna must be installed in a location not readily accessible to
children and in a manner that prevents human exposure to potentially
harmful levels of radiation.
Antennas mounted in Puerto Rico, the continental United States, or at
any site with a greater than 30° elevation angle must be installed such
that the lower lip of the antenna reflector is at least 5 ft above any
surface upon which a person might be expected to stand, and 3 ft
3 inches from any opening (such as a door or window) in a building or
adjacent structure.
Antennas mounted in Canada, Alaska, Hawaii, or any site with a less
than 30° elevation must be installed such that the lower lip of the
antenna reflector is at least 5 ft 9 inches above any surface upon which
a person might be expected to stand, and 3 ft 3 inches from any opening
(such as a door or window) in a building or adjacent structure.
The antenna must be mounted such that no object that could
reasonably be expected to support a person is within 6 ft 7 inches of the
edges of a cylindrical space projecting outward from the antenna
reflector toward the satellite.
If the above distance requirements cannot be met, the antenna must be
mounted in a controlled area inaccessible to the general public, such as
a fenced enclosure or a roof.
A fenced installation must have a locked entry, and the fenced area
must be large enough to protect the general public from exposure to
potentially harmful levels of radiation.
Access to a roof installation in a commercial, industrial, or institutional
environment must be limited by a door or a permanently fastened
ladder that is locked to deny access to the general public.
Once the transmitter becomes operational, maintain a safe distance – at
least 3 ft.
Failure to observe these cautions could result in injury to eyes or other
personal injury.

Chapter 3
Installing the antenna and radio
This chapter explains how to assemble and install the antenna, radio assembly, and
associated hardware.
Before you install the antenna, read all safety information in Understanding
safety alert messages on page 5.
General instructions for assembling the antenna
If you work on a roof, tower, or other high structure, or use a ladder or
scaffold to access the work site, follow these precautions to prevent personal
injury or death:








Walk only on sound roof structures.
Ensure that the antenna assembly and installation surface are
structurally sound so that they can support all loads (equipment weight,
ice, and wind).
Use safety equipment (e.g., a lifeline) appropriate for the work location.
Follow all manufacturer safety precautions for all safety and other
equipment used.
Perform as many procedures as possible on the ground.
To avoid electric shock, stay at least 20 ft away from power lines when
there is a chance that you or the equipment you are using could
accidentally come into contact with the power lines. Always look up and
check for overhead lines before moving a ladder.
If any part of the antenna or mount assembly comes in contact with a
power line, call the local power company to remove it. Do not try to
remove it yourself. If the antenna reflector contacts electric power lines,
you could be killed or seriously injured.
For pole mount installations, be sure to obtain information regarding
underground utilities in the proposed location before digging.

Assembling the antenna
Before you assemble the antenna, read these important instructions:

Sequence of steps – When you assemble the antenna, be sure to follow the
instructions in this chapter in the order they are presented.
For rooftop installations, assemble the antenna on the ground and then carry
the fully assembled antenna up to the roof.


Tightening hardware – Do not fully tighten any nuts or other hardware until
instructed to do so. See Table 4 for torque specifications.
Torque – To ensure successful installation of the antenna, it is critical that you
tighten all nuts and socket‐head screws to the torque values shown in

Select the installation site
Before selecting an antenna installation site, check OASIS or the installation
reference sheet to see if there is a customer preference for the installation site.
Work with the customer to see if a line of sight (LOS) is available at their preferred
site. Also, refer to the appropriate antenna site preparation and mount installation
guide that discusses the factors you should consider when selecting an installation
site.
The first and most important consideration when choosing a prospective site is
whether the site can provide an acceptable LOS to the satellite. Choose a site where
the antenna will be able to receive the strongest signal available. A clear,
unobstructed view of the southern sky is necessary for proper transmission. Also,
consider obstructions that may occur in the future, such as construction in the area
or the growth of trees.
Also, consider potential grounding sources when choosing a location. For guidance
on grounding, see the documents listed in Ground connections on page 46.
A local building permit may be required before installing the antenna. It is the
property owner's responsibility to obtain necessary permits and comply with local
building codes.

Chapter 3 • Installing the antenna and radio
1040579-0001 Revision A.04
Install the satellite modem
Note: You must install the satellite modem before installing the antenna to
determine the proper antenna pointing values (azimuth, elevation, and tilt).
For installation instructions, refer to the appropriate installation guide for the
satellite modem you are installing.
Determining the pointing values and polarization setting
Pointing values
Once the satellite modem is fully powered up, connect your smart device through a
wireless router and set the pointing parameters by accessing the satellite modem
System Control Center through your mobile browser (which can be launched from
within the OASIS app). If you need further guidance, consult the Ka-Band Antenna
Pointing Guide for Bent-Pipe Satellite Networks (1038764-0001).
Alternatively, connect the satellite modem to your laptop using an Ethernet cable,
and then use your global positioning system (GPS) receiver to calculate the exact
latitude and longitude of the antenna site. Follow the instructions in the Ka-Band
Antenna Pointing Guide for Bent-Pipe Satellite Networks (1038764-0001) to enter
the latitude and longitude information to determine the initial antenna azimuth,
elevation, and tilt values. Record these values and keep them handy for reference
as you install and point the antenna.
Polarization setting
At the satellite modem System Control Center, enter the installation parameters as
described in the Ka-Band Antenna Pointing Guide for Bent-Pipe Satellite Networks
(1038764-0001) to obtain the required polarization setting (either left‐hand circular
polarization [LHCP] or right-hand circular polarization [RHCP]). Make a note of the
required setting for reference when you install the radio.
Install the antenna mount
Before installing the antenna, you must first install a suitable antenna mount. If the
system requires a pole mount installation, be sure to obtain information about any
underground utilities in the proposed location. Have the appropriate utility
company mark the location of any underground telephone wires, storm drains, and
so on. Also, because soils vary widely in composition and load capacity, it may be
necessary to consult a professional engineer to determine the appropriate
foundation design.
If you are using the QUIKRETE fast-setting concrete mixture to set the pole mount, it
will take about 4 hours for the concrete to cure to the point where you can safely
install the antenna. See the appropriate antenna site preparation and mount
installation guide for more information about using QUIKRETE.
Mounts installed with a standard concrete mix need at least 24 hours to cure before
you can install an antenna on the mount. Be sure to plan and schedule the
installation accordingly.
Chapter 3 • Installing the antenna and radio
1040579-0001 Revision A.04
25
Note: Ensure the pole remains plumb as the concrete cures. You can accomplish
this by bracing the pole. Figure 7 shows an example of how to do this.
Figure 7: Pole mount kept plumb with guy wires
Note:
The antenna mast must have an outside diameter of 23⁄8 inches.
For complete information regarding antenna mount installation, including various
mounting methods, refer to the appropriate antenna site preparation and mount
installation guide.
Refer to the installation reference sheet for any customer-requested guidelines
concerning the mount installation. When you arrive at the site, only use the
installation method/location requested in the work order if LOS proves it to be the
best method/location.
If the installation reference sheet does not specify a method, you must use one of
the methods documented in the appropriate antenna site preparation and mount
installation guide. Most installations in commercial, industrial, or institutional
environments use a non‐penetrating roof mount.

Attach the polarization plate and reflector bracket to the Az/El mount, as shown in
Figure 8.
1. Place the reflector bracket against the face of the Az/El mount. Make sure
that the Az/El mount fits inside the lip of the reflector support. Then place the
polarization plate over the round opening in the reflector bracket.
2. Rotate the polarization plate so that the five holes line up with the
corresponding holes in the Az/El mount.
Note: The polarization plate contains additional holes that will not line up
with holes in the Az/El mount.
Figure 8: Attaching the reflector bracket and polarization plate
3. Insert five carriage bolts through the polarization plate and into the
corresponding holes in the Az/El mount.

4. From the opposite side of the reflector bracket, place a hex nut on each bolt
and tighten them lightly, only until snug. The reflector bracket should rotate
freely between the Az/El mount and the polarization plate.
When the reflector bracket is correctly attached to the Az/El mount, you can
see the tilt scale numbers above the tilt pointer, as shown in Figure 9. In the
figure, the tilt is set to 0.
The Az/El tilt scale can place the tilt or rotation of the antenna to either a
positive or negative position, based on coordinates, and must be set on each
installation according to specifications.
5. Using the tilt value you obtained from the satellite modem, as described in
Determining the pointing values and polarization setting on page 25, set the
scale to the proper reading and lock down the five bolts.

Installing the antenna reflector
Follow the steps below to attach the antenna reflector to the reflector bracket.
While attaching the reflector bracket, do not place the reflector face down on
a hard surface. The weight of the reflector bracket and any additional pressure
during assembly could bend the reflector.
1. Line up the holes on the reflector with the holes on the reflector support, as
shown in Figure 10.
2. Insert six thread-cutting screws (11⁄32-14 × 1.13 inch) into the holes in the
reflector bracket and through the corresponding holes in the reflector, as
shown in Figure 10.

1. Attach the side rods to the reflector dish using two 1⁄4-20 x 1 inch carriage
bolts. Loosely secure both bolts with a 1⁄4 inch flat washer, a lock washer, and
a hex nut. You should still be able to rotate the side rods.
2. Loosely attach the feed support arm to the side rods using a single 1⁄4 x 2 inch
hex bolt and two 1⁄4 inch flat washers, a lock washer, and a hex nut. The
washers must be placed on both sides of the feed support arm, as shown in
Figure 12.
3. Swing the feed support assembly upward and use a 1⁄4 inch flat washer, lock
washer, and hex nut to secure it to the reflector. See Figure 13 on page 32.

Installing the radio assembly
To mount the radio assembly to the feed support arm:
Note: Never mark the radio housing or feed horn. Marks cannot be removed and
will result in the unit being scrapped if it is returned to Hughes.
1. As shown in Figure 14, position the radio assembly above the adapter bracket
so that the waveguide end of the radio is nearest to the reflector.
2. Lower the radio onto the adapter bracket and insert one 5⁄16 inch × 2 inch
bolt, with 5⁄16 inch flat washer and lock washer, up through the feed support
arm and adapter bracket, into each of the two threaded sockets in the radio
transmitter.
Note: If you lose a screw that holds the radio on the feed arm, use a
replacement screw of the same size. Have spare nuts, bolts, or screws
on hand in case you lose those provided in the kit.
3. Tighten both bolts to secure the radio to the feed support arm.

Adjusting circular polarization
It may be necessary for you to reposition the polarizer waveguide on the radio
assembly to set the proper polarization between the radio transmitter and the
antenna reflector. There is no default factory setting for transmit polarization;
therefore, the radio may be shipped with either setting.
To check the polarizer setting and make adjustments (if necessary):
1. Check the installation reference sheet to determine whether the installation
calls for left-hand circular polarization (LHCP) or right-hand circular
polarization (RHCP).
2. Refer to Figure 15 and check the position of the polarizer waveguide on the
radio.
— If the marker aligns with the L, the polarizer is set for LHCP.
— If the marker aligns with the R, the polarizer is set for RHCP.
Figure 15: Determining the polarization setting
3. If the polarizer is not set in accordance with the installation reference sheet,
you must reposition it.
To reposition the polarizer:
1. Remove the two-piece clamp that secures the polarizer to the
transmit/receive integrated assembly (TRIA) by loosening and removing the
two hex socket (Allen) screws that hold it together.
2. Separate the polarizer from the TRIA and reposition it so that the marker on
the TRIA aligns with L for LHCP or R for RHCP, as shown in Figure 16 on
page 35.
Note: Be careful not to dislodge the O‐ring in the polarizer waveguide.
34
Chapter 3 • Installing the antenna and radio
1040579-0001 Revision A.04
Figure 16: Adjusting circular polarization (clamp removed)
3. After making the adjustment, reseat the waveguide with the TRIA and
reassemble the clamp as follows:
a. Position the lower half of the clamp (with threaded holes) against the
polarizer TRIA interface, as shown in Figure 17 on page 36.
Important: To fit into place correctly, the flat face of the clamp half must
align with the polarizer seam.
b. Position the upper half of the clamp (with unthreaded holes) against the
half already in place.
c. Start each spring-loaded Allen screw by hand, being careful not to cross
thread them.
Note: Because the screws are long, they can easily be cross threaded if
they are misaligned. If the screw does not turn easily when first
inserted, back it out and start again.
d. Use a 7⁄64 inch Allen wrench—do not use a power driver—to alternately
tighten the two spring-loaded screws. Tighten the screws until you hear a
click, signifying that they are fully tightened.
Note: The screws will continue to turn after they click, even though they
are fully tightened.

Attach the clamp exactly as described in the previous procedure and as shown
in Figure 17. Failure to do so could allow moisture to accumulate inside the
TRIA and/or feed horn, causing damage to the radio.

Do not remove the protective packing material from the feed horn
window until installation of the radio assembly is complete.
Do not attempt to remove the feed horn window at any time.
Be careful not to damage the feed horn window.
Do not touch the plastic film that covers the window.
To attach the feed horn to the radio assembly:
1. Remove and discard the protective seal from the polarizer on the radio
assembly, shown in Figure 18.

2. If one is not already present, insert the O ring into the groove inside the stem
of the feed horn, as shown in Figure 19.
Figure 19: Insert O-ring into groove at mouth of feed horn
3. Position the feed horn against the waveguide, as shown in Figure 20.
Figure 20: Feed horn position
4. Fit the two halves of the feed horn clamp around the ridge at the point where
the feed horn meets the waveguide, as shown in Figure 21 on page 39. When
properly aligned, the seam formed by the two halves of the clamp will line up
with the seam on the waveguide.

1040579-0001 Revision A.04
Figure 21: Attaching the feed horn clamp
You must assemble the collar exactly as described above and as shown in
Figure 21 before tightening the hardware. Failure to do so will result in
damage to the polarizer waveguide.
5. Insert the two hex socket (Allen) screws into the collar and tighten to secure
the feed horn in place.
6. At this point, fully tighten any hardware that is not tight—however, leave nuts
that are used for pointing adjustments slightly loose or just snug.

Installing the antenna assembly onto the mast pipe
Follow these steps to mount the antenna assembly onto the mast:
1. Before you install the antenna assembly onto the mast pipe, use a bubble
level to make sure that the mast is plumb.
Check the mast at two perpendicular locations, as shown in Figure 22.
Note: It is critical that the antenna mast is plumb. It is impossible to adjust
the antenna to correct for a mast that is not plumb.
Figure 22: Making sure the mast is plumb
2. Slide the Az/El canister down onto the mast as shown in Figure 23 on page 41.
3. Tighten.
Note: The outside diameter of the mast must be 23⁄8 inches.

This completes the assembly phase of the antenna installation process. Depending
on its orientation, the antenna should look similar to the one shown in Figure 24.
Figure 24: Assembled antenna
To proceed with the installation, you must route the IFL transmit and receive cables
between the antenna and the IDU. See Chapter 4 – Cabling, connections, and
grounding.
Chapter 3 • Installing the antenna and radio
1040579-0001 Revision A.04

Chapter 4
Cabling, connections, and grounding
This chapter illustrates where the antenna IFL connector is located, describes how
to route the IFL cable at the antenna, and explains how to connect the IFL cable to
the radio assembly. You must connect this cable before you can point the antenna
at the satellite.
Cabling requirements
For a list of approved coaxial cable types for the IFL cable that runs between the
antenna and the satellite modem, see the Hughes FSB, IFL Cable, Approved List
(with lengths) for Spaceway Domestic Installations (FSB_080202_01). The FSB lists
the maximum cable length for each approved cable type for all relevant radio types.
Coaxial cables and connectors can corrode if exposed to moisture. Use only
compression-type connectors, and weatherproof them with dielectric grease
and weatherproofing tape.
Note: For connector and ground block requirements, see the Hughes FSB, HN
Broadband Requirements for RG‐6 and RG‐11 IFL Cable Connectors, Ground
Blocks and Ground Block Location (FSB 50518_01).
Chapter 4 • Cabling, connections, and grounding
1040579-0001 Revision A.04
43
Routing the IFL cable at the antenna
1. Both IFL cables must run along the feed support arm, secured to the arm with
UV-resistant cable ties, as shown in Figure 25.
Figure 25: IFL cable configuration
2. Leave an adequate coiled service loop (6 ft to 10 ft) and use UV-resistant cable
ties to secure it to the mast, boom arm bracket, or Az/El mount, providing a
minimum cable length of 25 ft between the radio and the satellite modem.
Note:
— Do not leave the service loop lying on roof or other mounting surface.
— Do not block access to the azimuth and elevation adjustment nuts on
the Az/El mount assembly.
— Be sure to run a grounding wire from the Az/El plate to the ground
block.
3. Coil any additional cable and secure with cable ties.
Where the IFL cable connects to the radio or to a ground block, tighten the
cable connector to the torque specified in Table 4. Over-tightening the radio
connector can result in damage to the radio assembly.
44
Chapter 4 • Cabling, connections, and grounding
1040579-0001 Revision A.04
Connecting the IFL cable
This section explains how to connect the IFL cable to the radio assembly at the
antenna.
All outdoor F‐connector threads must be coated with dielectric grease before
connecting them to the radio or ground block. See Hughes FSB HNS
Broadband Requirements for RG‐6 and RG‐11 IFL Cable Connectors, Ground
Blocks and Ground Block Location (FSB 050518_01).
Connect the IFL cable to the radio as follows:
1. Ensure that the satellite modem is powered off and its power cord is
unplugged from the outlet.
2. Apply a small amount of dielectric grease to the inside of the IFL cable
connectors.
3. Connect the IFL cables to the connectors on the radio, as shown in Figure 26.
4. Tighten the cable connectors to 20 in-lb.
5. When the IFL cables are properly connected to both the radio and the satellite
modem, reapply power to the satellite modem as instructed in the satellite
modem installation guide.
Figure 26: IFL cable connector
Chapter 4 • Cabling, connections, and grounding
1040579-0001 Revision A.04
45
You must protect the radio connection with a weather boot or approved
weatherproofing tape; however, because the antenna pointing procedure
requires that you disconnect the IFL cable, wait until pointing is complete
before weatherproofing the connection. For additional information, see
Weatherproof the cable connections on page 51.
Ground connections
Properly ground the antenna assembly in accordance with all local and
national electrical codes.
The antenna assembly must be grounded. For grounding information, refer to your
training, best grounding practices, Hughes Field Service Bulletin (FSB) HNS
Broadband Requirements for RG‐6 and RG‐11 IFL Cable Connectors, Ground Blocks
and Ground Block Location (FSB 050518_01), and applicable parts of the National
Electrical Code (NEC).
Antenna mast
Ground the antenna mast at the Az/El mount. For specific grounding procedures,
refer to the documents listed above.
Radio
Although the radio contains a ground screw on its underside, use of this ground
screw is optional. The radio is grounded through the shield in the coaxial cable and
the ground block, and no additional grounding is necessary. For additional
grounding procedures, see the documents referenced above.
Pointing
This completes the installation. You must now point the antenna. See the Ka-Band
Antenna Pointing Guide for Bent-Pipe Satellite Networks (1038764-0001) for
details. For mechanical adjustments specific to this antenna, see Adjusting elevation
on page 47.

Chapter 4 • Cabling, connections, and grounding
1040579-0001 Revision A.04
Chapter 5
Adjusting antenna azimuth and
elevation
This chapter explains how to adjust the antenna azimuth and elevation for optimum
transmission and reception. It explains mechanical adjustments only. For
explanation of the pointing process for this antenna, see the Ka-Band Antenna
Pointing Guide for Bent-Pipe Satellite Networks (1038764-0001). To successfully
point the antenna, you must follow the procedures as described in the pointing
guide.
Do not pull on the antenna reflector or feed support arm to make pointing
adjustments. Doing so could cause permanent damage to the antenna.
Instead, use the adjustment mechanisms and procedures described in this
chapter.
Adjusting elevation
Figure 27 illustrates how to adjust the antenna elevation by moving the antenna up
and down relative to the horizon.
Figure 27: Adjusting antenna elevation
Chapter 5 • Adjusting antenna azimuth and elevation
1040579-0001 Revision A.04
47
To adjust antenna elevation:
1. Loosen the elevation lockdown nuts on each side of the Az/El mount. See
Figure 28.
Figure 28: Elevation adjustment components
2. Loosen the top elevation adjustment nut and spin it counter‐clockwise until it
is an inch or two up the elevation adjustment rod.
3. Use the lower nut to adjust the elevation.
The white line shown in Figure 29 points to the elevation value on the
elevation scale. The antenna shown in Figure 29 is adjusted to 26°.
Arrow points to the elevation marker (below bolt).
Figure 29: Elevation marker
48
Chapter 5 • Adjusting antenna azimuth and elevation
1040579-0001 Revision A.04
4. Spin the top elevation adjustment nut clockwise until it is snug against the
base plate.
5. Secure the coarse elevation setting by tightening the two elevation lockdown
nuts on either side of the Az/El mount.
Adjusting azimuth
Figure 30 illustrates how you adjust antenna azimuth by moving the antenna
horizontally, from side to side.
Figure 30: Adjusting antenna azimuth
Checking the azimuth base starting position
Before making any azimuth adjustments, ensure that the azimuth lockdown bolts
are centered in the curved slots in the azimuth base. See Figure 31 on page 50.
If the bolts are not centered in the slots:
1. From underneath the azimuth base, ensure that the four 5⁄16 inch azimuth
lockdown nuts are loose.
2. Use a 1⁄2 inch wrench to turn the fine azimuth adjustment bolt until the
lockdown bolts are centered in the curved slots.
You should not have to turn the two inner nuts on the adjustment bolt, but if
they are loose, tighten them.
Because this is a fine adjustment bolt, you may have to turn it many times.
Leave the lockdown nuts loose so you can adjust azimuth.
Chapter 5 • Adjusting antenna azimuth and elevation
1040579-0001 Revision A.04
49
Figure 31: Checking the azimuth base starting position
Coarse azimuth adjustment
Make coarse azimuth adjustment as follows:
1. Loosen the three Az/El canister nuts shown in Figure 32 enough to allow the
antenna assembly to rotate freely on the mast.
Figure 32: Az/El canister nuts
2. Holding the reflector bracket, point the antenna reflector as accurately as
possible in the direction indicated in OAISS or on the installation reference
sheet.
3. Lock down the Az/El canister by fully tightening the three canister nuts.
50
Chapter 5 • Adjusting antenna azimuth and elevation
1040579-0001 Revision A.04
Fine azimuth adjustment
For fine azimuth adjustment, use the azimuth adjustment bolt:
1. Ensure that the Az/El canister nuts are tight enough to prevent the antenna
from rotating on the mast.
2. Using a 1⁄2 inch wrench, rotate the azimuth adjustment bolt shown in
Figure 32 on page 50 in either direction to achieve the desired azimuth angle.
Do not pull on the antenna reflector or feed support arm to make pointing
adjustments. Doing so could cause permanent damage to the antenna.
3. When the azimuth is set as desired, tighten the four azimuth lockdown nuts
under the azimuth base.
Weatherproof the cable connections
Hughes radio connectors, in conjunction with the dielectric grease, provide
weatherproofing for outdoor connections. These connectors should be used in
new installations, upgrades, and repairs for audits.
You must further protect radio connectors by wrapping them with
weatherproof tape, such as GB Electronics silicone tape, or by covering them
with a full‐length weather boot that has been filled with dielectric grease.
Weatherproof and secure all cable connections, as shown in Figure 33 on page 52.
1. Apply a small amount of dielectric grease to the inside of a coaxial cables
weather boots and place the weather boots on the radio connectors, or wrap
the connectors and cables with weatherproofing tape and secure the tape
with a cable tie.
If you use tape and cable ties, they must be resistant to ultraviolet rays.
