Not sufficiently... the bracket is against a painted surface, but I also have a new theory brewing.
I'm wondering if grounding to the body versus the frame would be better for an antenna application. Seeing that the metal surfaces of the body act as part of the antenna and the body is pretty much isolated from the frame, grounding directly to the frame may not be the most appropriate point in this application. Just a theory, but I'm going to give it a try.

The body attaches to the frame in many places. Grounding to one of the other "should" be the same. However, RF grounding is more picky then electrical grounding so who knows?
Your SWR can change with your doors open and closed. I wonder how much or if my SWR will change when I take the doors of my jeep this summer?

Yes, it is attached in many places, but there also rubber isolators so I'm not sure how "clean" the path would be. It's just a theory that I'm going to test with the hopes that going directly to the body will be more antenna-friendly. I guess if my SWR levels change while retesting in the same spot, I'll know that something was affected and can try tuning from that point.
Post up what you find out.
That must be the biggest fiberglass antenna in the world!
Looks like that 4runner is electrically powered from the overhead powerlines- like those old school bumper cars.

I hope you got a quick disconnect crashman! Hahaha. Good God that should be GREAT on the highway, assuming you choose the route with no bridges under 20 feet :lookout:

you mean 1:0? I think just 0 would be no signal at all.

Can you post some pictures of the antenna mount? I am interested in how you did it.
He probably has a 1:1 SWR or zero movement on the meter... he's got quite an antenna on there!. Excellent TX and RX, too.
Your right 1:1 would be the lowest.

He converted a door jam mount. There is a guy selling some custom mounts but you'd have to see if it would work as I've only seen them on 3rd gens. http://www.toyota-4runner.org/showthread.php?t=108448

I decided to make my own CB antenna mount in order to move the antenna further out so it would be out of the way of the rear hatch. I was getting a little tired of having to pull the antenna out of the way every time I opened an closed the hatch. So, borrowing some design cues from the 3rd Gen mount made by a forum member and using the mount I made for the FireStik mount, this is what I did.
Polished...
Then I used a scotch-bright pad to give it a satin finish...
It'll have a matte clear topcoat when I'm done so it should be well protected.
