Hey everyone, trying to get my SWR dialed for the CB radio, Uniden Pro 520xl, 10ft male to male coax cable, 2' firestik on the teraflex taillight mount. Cannot get my SWR below 3, its around 3.7 ish no matter what I do. I used a dremel to get a clean ground for where the extra mounting bolt goes, but that solved nothing. There are no kinks in my cable, and my uniden is brand new. Could my SWR be high due to it being so close to my GMRS antenna? Heres a pic
