Connecting the transmit
and receive cables
This section explains how to connect the transmit and receive
cables to the radio assembly.
Transmit cable
Connect the transmit cable to the transmitter as follows:
1. From inside the building, disconnect the IDU power supply.
2. Go outside and connect the transmit cable (marked with blue
electrical tape) to the transmitter connector marked IFL.
Figure 41 shows the transmit connector location for the
J-type radio assembly, and Figure 42 shows the connector
location for the cradle-type radio assembly. In both cases the
connector is a female F connector.
3. Use a
7
/16-inch torque wrench to tighten the connector to
20
inch-lb.

moisture. Use only compression type connectors, and
weatherproof them with dielectric grease and weatherproof
tape.
