Connecting the transmit
and receive cables
This section explains how to connect the Tx and Rx cables to the
radio assembly at the antenna.
Transmit cable
Connect the Tx cable to the radio transmitter as follows:
1. Remove power from the satellite modem.
2. Connect the Tx cable (marked with blue electrical tape) to the
transmitter connector marked IFL, shown in Figure 28.
3. Tighten the cable connector to 22 in-lb with a torque wrench.
4. Apply dielectric silicone grease to the connection.
5. If necessary, secure the cable with cable ties.
Note: You should secure all cable connections with
dielectric grease and weatherproofing tape as shown in
Figure 27. However, because the antenna pointing procedure
requires that you disconnect the cables, you should wait until
the pointing process is complete before weatherproofing the
connections.

CAUTION
Coaxial cables and connectors can corrode if exposed to
moisture. Use only compression type connectors, and
weatherproof them with dielectric silicone grease and
weatherproofing tape.
