Tuning your antenna using the Cobra® 29 LX:
Turn the radio on.
Set to Channel 40.
Push the S/RF/CAL/SWR button next to the meter to “CAL” for calibration.
Press and hold the mic button.
Adjust the SWR CAL knob on the bottom right until the meter swings right and sets to “CAL” on the meter.
Keeping the mic button depressed, press the S/RF/CAL/SWR button again and switch to “SWR” and write down the SWR reading on the meter.
Repeat the steps above on Channel 1.
Use your SWR readings to make adjustments to your antenna accordingly.
If channel 40 SWR is higher than channel 1 SWR, lower/shorten the antenna. If channel 1 SWR is higher than channel 40, lengthen/extend the antenna. The goal is to have the reading be similar and both be under 2 or lower (ideally).
