Message:: [QUOTE="Night Stalker10, post: 11640395, member: 200038"]Your biggest mistake is trusting the cobra 29 swr readings to adjust your new antenna. I had a fellow company driver complain about his new cobra 29LX not receiving or getting out very good. The Wilson antennas on his truck were rusty at the mounts and coax connectors. My antenna analyser showed a very high swr reading of 5 - 6 for swr.  No surprise there. The cobra 29 swr meter showed a reading of 1.2. That seems to be the magic number for swr readings with these radios, no matter what the real swr is. The swr vr6 pot inside the cobra 29's are always out of adjustment from the factory. I would trust the cheap truck stop external swr meter any day before the cobra internal swr meter. I'm confused by what you mean by loud and clear 1.2 swr reading on your radio. You claim your getting out and receiving good, but that doesn't explain the high swr reading with the external meters. Did you install the coax connectors on the coax yourself?  There's a problem in your antenna system somewhere. Never trim and tune an antenna by the radios swr meter. At least not the cobra 29s.[/QUOTE]
