I have a new bearcat 980 cb with a K40+ antenna. My SWR reading on channel 1 is 3.0 and channel 40 is 3.4 . I cant seem to get it any lower . I have replaced the mount for the antenna and checked the cable and all looks good ... been going at this for hours ..... anyone have any ideas? I’m driving a 2018 freightliner m2-112 ... please help !!!!!!!!
