8.6.6 Connecting Jumper Cable with Feeder Cable and Sealing Their Joint
Caution:
Pay attention to the sealing of the joint between the feeder cable and the jumper
cable, which is critical in the installation of the antenna feeder system. Use
waterproof adhesive tape for the sealing.
Generally, the 3m-long 1/2” jumper cable is used to connect the antenna and the
primary feeder cable. Connect the 1/2” jumper cable with the primary feeder cable and
then seal their joint as follows:
1. Connect the antenna jumper cable with the connector of the primary feeder cable
and then screw down the connector.
2. Treat connectors with waterproof measures. The procedures are as follows:
1) Wrap the waterproof adhesive tape around the joint from the sunk area upward
(fill the area with the tape), as shown in Fig. 8.6-10.
Fig. 8.6-10 Schematic Diagram of Wrapping Waterproof Adhesive Tape (1)
2) Stretch the tape with force and wrap it in the same direction as for fastening the
cable connector.
3) Wrap circularly in the reverse direction for the second layer, as shown in Fig.
8.6-11. Note that the next circle covers 1/3 of the previous circle for the purpose
of preventing inleakage of rain. Wrap the joint for three layers totally. Do not cut
the adhesive tape during the wrapping. The length of the cable wrapped with the
tape should be 20mm longer than that of the connector.
