3. Coil the extra cable, leave a drip loop, and secure the transmit
cable with cable ties.

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.
