1 - Park the vehicle as far away from buildings and power lines as possible, and keep the doors, hood, and trunk closed tight. Instruct those around the car to step back at least 10 nyards, but the further the better for accurate results.
2 - Connect an SWR (standing wave ratio) meter to the CB, and place the CB on channel 1. Press the button on the microphone, known as "keying up," and adjust the knob labeled SET until the needle reaches its highest point. Then set the meter on REF, and key up again. Write this number down so it can be referenced later.
3 - Turn the CB to channel 40, and key up again while in the REF mode. The needle level while on channel 1 should match or nearly match the level recorded on channel 40. If the needle reading on channel 40 is higher than while on channel 1, the antenna is too long. If the needle is lower on channel 40, the antenna is too short.
4 - Adjust the antenna by either cutting off a quarter inch with a good pair of dykes and retesting, or raising it up a quarter inch if possible. Repeat these steps until the signal strength on both channels 1 and 40 are exact, or very close.
