Just a quick comment, because almost every mobile antenna set-up has a different challenge often a 1/4 wave over whatever ground that a vehicle may present to the antenna you might not necessarily see a perfect 50 ohm match at resonant length of the antenna.
Sometimes it can take a small correction to get things to balance out.
I think this is what propagates the old Cb myth that you must trim the coax on a 1/4 wave antenna to make it work right.
I do think the user here has put in a diligent effort to try to understand what he is up against.
I really think he was on the right path as far as the antenna, the drive level into the amp i think is the killer here.
Simply reducing drive levels and leaving the antenna system alone should be all you need.
Cb style amps are almost always over rated and create more complex problems sometimes.
