Hi everyone I am new to GMRS but old CB'er. I put in a Midland radio in my truck. ( It's a recycled beer can truck ) So a mag mount will not work. The cheep little antenna mag mount gives me a 1 1.2 swr. The ghost antenna gives me a very high swr. 1:2.5 with RG8X. Does coax type matter? There is no shorts is the coax. Any help would be greatly appreciated. I'm about to walk away from GMRS. P.S. radio in Side X Side is same setup, but RG58 NMO mount from Midland. SWR 1:1.3. Thank you Chance WRJT366
