I just got the Cobra 29 LX LCD and was wondering how I can get rid of the antenna warning. The radio is in a '12 Cascadia with dual antennas that came with the truck. Would removing one solve the issue? SWR. Reading is (according to the radios meter) .5 on 40, and a bit over 2 on 1 and 20. I tried the SWR CAL dial but no change. Thanks for any help!
