Question about Cobra 29 LTD CB Radio
I done a peek and tune on my cobra 29 ltd classic and upgraded finals now the ant light comes on when I talk on it but the swr is fine. how do I fix this?
Your SWR is probably NOT fine. You need to use an external meter if you have had work done to the radio. Especially if you have had a swing mod done to the radio. When you do this, the dead key of the radio is lower then the calibration knob on the radio can adjust for. It will always come up lower then it actually is.
Your radio might have been fine before the work was done on it because it was putting out very little power. Now you are most likely putting out 50 watts or more. Big jump from 4 watts.
When your raise the power in a radio, you will notice more when the antenna is not properly tuned.
In most cases with a stock CB, even when the antenna is not even near tuned, you will get a reading less then 1.5 anyway.
the more power you put out, the more important it is to have a good match.
But an external SWR meter, and check it. be careful if the ANT light is on.
You might also want to check your coax, connections to it, and your antenna for anything wrong.

Don't worry about that I had the same thing on my Cobra 29ltd classic. It does that when you are running around 40 watts power out with Swr 1.3(its just a red light that shows you are talking after you have the mod done to it. Mine would talk to Oklahoma from Kentucky on USB Ch # 39 Amazing how much it improves it to have mod & upper channels installed.
