ADJUSTING THE STANDING WAVE RATIO
Most antennas are factory adjusted. However, you can usually improve per- formance by matching the characteris- tics of your antenna system to the CB's RF output power using the
After you have properly installed the an- tenna and routed its cable, follow these steps to adjust the standing wave ratio

1.Turn on the CB by turning OFF/VOL- UME clockwise until it clicks.
2.Set S/RF/SWR/CAL to CAL.
3.Hold down the microphone's talk button and adjust SWR CAL so the SWR/RF signal meter's needle
points to CAL 
on the upper SWR scale.
4.Release the microphone's talk but- ton.
5.Set S/RF/SWR/CAL to SWR.
6.Press the microphone's talk button again and note the actual SWR measurement on the upper SWR scale. See the chart on Page 10 for help in interpreting the SWR meter readings.
The SWR value takes into account the actual frequency of the RF signal trans- mitted. Therefore, you will get a different SWR reading from one CB channel to another. Almost all the CB transmis- sions usually fall within an acceptable range. However, for optimum radio per- formance, we recommend that you fine tune the antenna's system based on the channel you use most. If you have no particular channel preference, set your antenna's SWR for maximum perfor- mance on Channel 19.
