I recently installed a uniden CB radio with a firestick antenna mounted on the back of my EVO tire carrier. Extended a ground wire on to the carrier to chassis ground, ran coax cabling etc and when checking the SWR meter I keep getting around 3. I swapped to a different coax cable same result, verified ground connection etc. Kind of lost on this one, never had this type of issue before looking for suggestions. I went through the guide at rightchannelradios as well for a sanity check.
