requirements

of cables

After testing the antenna system, make waterproof processing for cables at the positions

where cables connect.

After an installed antenna system passes the test, use waterproof insulated tapes and PVC tapes to

make waterproof processing for cables at the positions where jumpers connect to the tower amplifier

and the positions where jumpers connects feeder cables.

To protect the cables against water and avoid the standing wave alarms, create waterproof curves at

the positions where jumpers and feeder cables connect.

Use the tape to wrap a jumper where it

connects to another cable
