I'm new to CB so please forgive me. I am currently restoring my 1998 Dodge ram 2500 regular cab. I have turned my attention to the interior. The headliner needs to be recovered. The cb is mounted on the interior cab roof. The antenna is on the cab (center) and the cable runs straight back, then to the driver door, then along the top to the front center where the extra is wrapped in a figure 8. With the headliner removed I get less than 1.5 on the radio swr. If I put the headliner on it jumped up over 2. So I put a piece of foam underneath the figure 8 and that brought it down to 2ish with the headliner. I also have a 4 foot firestick I could moount on the headache rack. Should I splice the wire to make it shorter to remove the figure 8? Or is there something else I should try. Radio id a Galaxy 959 and the antenna is a Wilson little wil. Thank You!!!!
