1. REPLACE ANTENNA ELEMENTS.
2. REMEASURE FORWARD/REVERSE
POWER*.
* NOTE, RVS PWR QUICK CHECK:
1. Measure FWD PWR (e.g., 4.6 W).
2. Measure RVS PWR (e.g., 1.2 W).
3. Divide FWD PWR by RVS PWR (e.g., 4.6/1.2).
4. If result is 3.0* or MORE, RVS PWR is normal.
5. If result is LESS THAN 3.0*, RVS PWR is high,
troubleshoot.
6. * If radio is used for data transmission,
a result of 4.0 or more is desired.
