CB Antenna Ground

Question for people who know more about antennae than I do..

I'm going to use a Teraflex taillight mount for my antenna, simple stud mount, PL259 connector. I've never used a stud mount before, fwiw. I've sanded off part of the coating on the underside, and got good conductivity between the mount and the bottom of the stud, no conduction between the top of the stud and the mount, so I know I got that right.

If I used a ring / spade terminal bwteen the mount and "ground" side of the stud, would that be sufficient for attaching & running a ground wire?

Thanks!

If the Teraflex bracket is installed correctly it will not need any extra grounding wires. Remove just enough paint and powder-coat to have bare metal contact between the Teraflex bracket and the Jeep tub, or use some grounding washers from the Hardware store between the bracket and the tub. When completely installed, you should test for continuity between the knurled part of the PL-259, to the bracket, and to the Jeep tub.

See this on Stu's site about the Teraflex brkt - http://www.stu-offroad.com/cb/tfmount/tfmount-1.htm

Thank you Tim! Great link (and I wish I did my sanding that neatly :-X)

You're the second person to recommend star washers; I'll probably do that.

I didn't use any washers, or take any paint off the tub, and my grounding and SWR are fine. I just used a file to remove all of the powdercoating from inside the bolt holes as well as around the edge of the bottom of the antenna hole, and used a FireRing connector.
