Connecting RF Cables
1.
Make sure each RF cable and its connectors are absolutely dry.
2.
Loosely connect all the RF cables from each antennaRF port to the
corresponding A8 BTS RF port. Do not tighten up any of the connections.
3.
Secure the RF cable bundles to the pole.
4.
Starting from the back row, tighten the RF cable-to-A8 BTS connections and
apply sealing materials to them, work your way from left to right, in the order of
ports 1, 3, 5, 7. Unplug other RF cable-to-A8 BTS connections to make room if
necessary. For a detailed description on the weatherproofing procedures, refer
to the sub-section “RF Cable-to-A8 BTS Connection.” Repeat this process for
the RF cable-to-A8 BTS connections in the front row, work your way from left to
right, in the order of ports 2, 4, 6, 8. Unplug other RF cable-to-A8 BTS
connections to make room if necessary.
5.
Start tightening RF cable-to-A8 antenna connections and apply sealing
materials to them. Unplug other RF cable-to-A8 antenna connections to make
room if necessary. For a detailed description on the weatherproofing
procedures, refer to the sub-section “RF Cable-to-Antenna Connection.” Take
extra care not to twist the RF cables excessively, as it may cause the already
sealed RF cable-to A8 BTS connections to loosen.

RF Cable-to-A8 BTS Connection
1.
Tighten a RF cable-to-A8 BTS connection with a torque wrench to the proper
torque limit to ensure that correct internal seals and surface contacts are
made. If a torque wrench is not available, first tighten the connection to
finger tight, then tighten it with a wrench for an additional ⅛to ¼ turn from
the finger tight position.
2.
Start wrapping a layer of electrical tape from 1/4” (6mm) above the edge
of the cable connector. Overlap the tape to half –width. The tape should cover
the cable connector body, and extend 1” (25mm) above the cable connector
