Below is something that was sent to me as to a CB radio. Any input as to if I need it. Bob Dunahugh
CB radios operate on channels 1-40, and one antenna cannot provide ideally tuned reception for all of those. Most people opt for the middle ground and tune the antenna for best reception at the mid-point. One easy way to tune an antenna is to cut it to length according to the frequency that you want it tuned for. The measurement instrument that's used for tuning is an external Standing Wave Ratio (SWR) meter. That meter will also help with trouble-shooting your equipment to find a bad coax, a poorly grounded mount or a weak or non-functioning ground plane.
I personally think this is a good idea for the trouble shooting aspect of any cb
