4. d to the channel frequency It must be tuned to resonate optimally on all channels of the transceiver Channel 1 requires a longer antenna than Channel 40 because it Is lower in its frequency of operation Due to the various methods of adjusting antennas for proper S W R we have chosen what we think Is the optimum method Antenna with adjustment screws set screws 1 Starts with the antenna extended and tighten the setscrew lightly enough so that the antenna can be lightly tapped with your finger for easy adjustment 2 Set your transceiver to Channel 20 Press the PTT push to talk switch and tap the antenna making it shorter The S W R meter will show a lower reading each time the antenna is lapped By continuing to shorten the antenna you will notice the S W R reading will reach low point and then start rising again This means that you have passed the optimum point for Chane 20 Extend the antenna a short distance and again follow the procedure above When the lowest point has been reached switch to Channel 1 and then to Channel 40 and compare S W R readings They should be almost equal NOTE The proper selting is achieved when the SWR is 1 5 or below and when it has similar reading for channels 1 and 40 8 Antennas which must be cut to proper length 1 Follow the same procedure as above but adjust the length by cutting In 1 8 increments until good match is obtained 2 very careful not to cut too
