Connect the connectors, and measure the cabinet top jumper for
the antenna feeder performance indexes by an antenna feeder
analyzer (SITE MASTER), and then make the waterproof treatment
to the waterproof bend and connectors.
Note:
In the process of making waterproof treatment to the connectors of the
antenna feeder system, make sure that:
Wrap it with waterproof tape, sealing tape and insulating tape in turn.
The jumper should be bent softly without too large angle, and generally, the
bend radius is over 15 times of the jumper radius.
Insulating tapes should be wrapped from the bottom to the top in case of
rainwater leaking.
