Maybe try a piece of rubber/insulation and use it between the rack and the antenna mount. maybe 1/8 or so thick..make small strips and add until the SWR gets to a good reading with the antenna grounded.

I am about to go shopping for my CB antenna and was going to mount it onto the roof rack using clamp hoses and a piece of aluminum.. but wanted to insulate it from scratches and isolate it from the rack.
Here is what someone posted for me a few weeks ago, and was going to try something like this

Superjens web page

Let us know how is goes and what you found. smile

Good luck

I note form SuperJens' site that he did *not* insulate the antenna bracket from the roof rails and he did *not* use a separate ground wire for the bracket. So much for grounding to the truck instead of the rack?
