Question about Cobra 148 GTL 120-Channels Base CB Radio
It sounds like you may have damaged the RF power amplifier stage of the CB. Since you were adjusting the antenna characteristics. Did you have a SWR (Standing Wave Ratio) meter connected while you were tuning the unit? If you did you might have noticed the needle go past the 1.2 mark when you were adjusting the antenna or the unit itself. In any event I think that the RF power Amp is shot.
