Hi all,
I have Freightliner M2 that I have a Cobra 29 Classic installed in. I have the SWR calibrated using an external Astatic SWR meter. Truck running windows closed. . . etc. The SWR is around 1.2-1.4. The issue I have is every time I put the CB in the cubby and key the mic I get the Antenna warning light. I pull it out and everything is back to being as it should be. I don't have an issue with mounting the CB on the dash but would prefer the cleaner look of having it mounted in it's "cubby". Any thoughts as to why this would be occurring?
Thanks!

If you've confirmed the SWR is good with the radio in the cubby, you can always adjust VR6 to get rid of the antenna warning light.

I know in my truck there is alot of electrical crap up there & was told it's probably due to that, radio checks out just fine & was never told it sounded like i had any issues.
So as long as your running a good coax, antenna & radio has been peaked & tuned, from my experience you should be just fine run it & see if anyone says you sound muffled or distant. -
Are you coiling the coax tightly to make it fit?
I would check a few things before calling it good. Make sure the connections are tight at the back of the radio and wiggle/bend the coax while keyed up to see if it happens. -

I bet radio and or coax is getting too near other circuitry in or near the cubby. My bet is on the coax.

Let’s start with the basics, my first question is how old is the coax and what kind of connection is on the end of the coax?
then my second question is this, how much clearance between the radio and the front of the ‘cubby’?
