8.9 Waterproof Processing of Connectors
Follow the steps below to seal the joints between two cables:
1.
2.
1) Wrap the joints with the waterproof adhesive tape from the top of the connectors.
2)
3)
4)
5)
After the antennae are installed and all feeder cables are connected, measure the
standing wave ratio of them.
Measure one end of the indoor 1/2" jumper cable, which is to be connected with
the cabinet, with the tester. The standing wave ratio should be lower than 1.5. It
is best to be lower than 1.3.
Record the Voltage Standing Wave Ratio (VSWR) value and provide the VSWR
testing diagram.
Fasten the relative joints.
Implement waterproof processing to the joints.
The first layer should be wrapped in the same direction as for fastening the cable
connectors.
Stretch the tape with force and wrap it circularly for three layers totally. Note
that the next circle covers half of the previous circle, and the wrap stops at the
position about 10cm away from the joint.
Grip the joint with force to make the tape stuck firmly with the joint.
Wrap two layers of PVC tape around the waterproof adhesive tape in the same
way as for wrapping the waterproof adhesive tape.
Finally wrap a layer of anti-ultraviolet tape.
