Since this is a multi-generational question, I felt it best to ask here.
I have a Cobra 29LX with a 4' Firestick. Worked perfectly the first time I went out, then about half way through the day I started getting an occasional "CB antenna warning" error on my display. I believe it was still working fine as I could hear others just fine.
Fast forward to today, I'm getting ready to head out tomorrow so I decided to fire up the CB again and check my SWR readings. Every time I key the mic I get the antenna warning. The firestick is mounted with a spring to a conical base that's plastic with a grounded core. The mount location is my spare tire carrier (I know, not the best ground, but it's what I've got to work with). At any rate, my SWR readings are all under 1, on channel 1, 20 and 40. I did adjust the antenna slightly and the warning is now intermittent, but still there.
Thoughts? Could it be my ground? I like my mounting location and would really hate to have to change it. I could possibly run a 12awg or 16awg jumper wire from the tire carrier to the interior of the tub to really ground the carrier if that would help.
