I'll try to keep this brief, but I've discovered an interesting issue with my 2013 Jeep.
I have a stainless steel antenna bracket mounted to the rear gate of the vehicle (Teraflex 4997101). I'm aware this is a compromise location but for the sake of this discussion let's look past that. Attached to this I have a 6ft fiberglass antenna which shows no deflection on ch 19, and 1.1:1 or so on either end of the dial.
From one of the 2 bolts on the mount I have run a jumper of tinned copper strap to the tailgate with paint ground to bare metal. From there I have another jumper run to the metal body in the same fashion.
For some reason, when I lock the doors (which includes the tailgate) the SWR shoots up to 2:1!!!
I have swapped or tested every component. New stud(s), 2 different external SWR meters, new coax (including jumper to SWR meters), different radio, different antenna (Wilson 2000 w/10" shaft). What could it be?
