Ground connection
3. Coil the extra cable, leave a drip loop, and secure the transmit
cable with cable ties.
4. Route the receive cable (marked with red electrical tape) over
the Az/El mount assembly, behind the reflector, and along the
feed support tube to the TRIA, in a configuration similar to
that shown in Figure 38.
Do not exceed the minimum cable bending radius.
5. For the receive cable, leave a 138-inch service loop (11.5 ft),
secured to the mast, Az/El mount assembly, or reflector
bracket. This allows 10 ft for a service loop plus 18 inches for
installation of a future Ka-band radio upgrade.
6. Coil the extra cable, leave a drip loop, and secure the receive
cable with cable ties.
Note: When you connect the cables, tighten all radio and
ground block connectors with a torque wrench to 20 inch-lb.
Ground the transmitter and mast. For specific grounding
procedures, refer to the sources listed in Grounding on page 4.
Figure 39 shows the location of the ground screw on the J-type
radio assembly. Figure 40 shows the ground screw on the
cradle-type radio assembly.

Note: The transmitter may look a little different than the one
shown in Figure 40, but the connectors are still on the end of the
transmitter, as shown, and they are clearly marked: GND – ground.
IFL – interfacility link, for transmit cable.
