I like the new location. I didnt get a chance to hook up my SWR meter to see if there's an improvement from my bumper.

You're not grounding the mount? Be carefull.... CB's are one of those things that just because it seems to work, doesn't mean its installed correctly. You can ruin your CB that way.

I'd verify that you do indeed have NGP:

....otherwise, throw that ground back on.
