9.4 Test of Antenna Feeder System
1. After the antennae are installed and all feeder cables are connected, measure the
standing wave ratio of them.
2. 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.
3. Record the VSWR value and provide the VSWR test diagram.
