SWR Problems with Wilson Flex Antenna

Hey everyone, I just installed a Wilson Flex 4' CB antenna and I mounted it on the bedrails with a mirror mount (pictures below). I have been trying to tune it, but it's been giving me a reading of roughly 3:1 across the board from channel 1 to 40. I think this might be due to a grounding issue, but I don't really know what to do to remedy it. I know there are some others on the board here who run a similar mounting setup. What do you think? Input? Advice? Am I missing something entirely? Thanks for your help!

 

the ground is the problem. you need to make a ground wire and go from where its grounded there on the mount to the frame somewhere. i used a solid piece of cable to ground mine,.....but some 8 gauge wire should do the trick.

 

great! thanks for the quick/ helpful reply!

 

anytime man. let us know what the swr is after you reground.(be sure to leave the current ground where it is....just add one from that point to the frame)

 

will do. its probably going to have to wait till sunday though. date night tonight then weekend in southwest va with some of my buddies on the new river.

 

have fun man!

 

This article says that you don't have to use that cable.
