21.2 Connect a powermeter and dummyload directly to the Ant-port.
21.3 Connect a 10W VSWR meter DIRECTLY to the TX-port. Connect a transmitter to the VSWR-meter.
21.4 Adjust the transmitter exactly to the downlink-frequency (Tx-frequency of the repeater).
21.5 Tune the "Tx"-finetune-bolts at first for about maximum output, at the same time observing the VSWR. Begin at the "Ant"-side and work backwards to the "Tx"-side.
21.6 Then FINE-TUNE FOR MINIMUM =VSWR=, at the same time observing the output, beginning at the "Tx"-side, working towards the "Ant"-side.
21.7 Repeat the finetuning to MINIMUM VSRW.
21.8 VSWR should be lower then 1:1.5 (1:1.2), and insertion loss should be abt. 4 dB.
21.9 Lock all tuning-rods with thermal glue (see "cn.gif").
