Basically, yes. The one near the battery protects the Jeep, the one near the CB protects the CB.

Here's a pic with a fuse holder near the battery:

Default That's exactly the set-up I went with.

To be honest with you, I didn't really get why so many guys (and gals) were having problems figuring out where to mount their CBs. I've got a Cobra 29 LTD Army and under the dash on the passenger side was my first (and really, only) thought for a mount location. Personally, where I can see it looks cool to have it overhead, I wouldn't be able to stand the mic cord hanging down and swinging around when out playing in the dirt or snow. I do wish I had gone with a smaller CB like you did but I already had this one from prior vehicles so I used it. My wife would prefer more leg room but we all must make sacrifices.

Default Thanks for your help, Wolf.

In layman's terms all you are doing is ensuring that the gate and tub of the Jeep are tied into each other electrically. I would take a few feet of the strap, attach one end to any bolt on the gate, another on any bolt in the Jeep. Keep the run as short as possible. The pictures show how I routed it, and there are several options to choose from as far as stock bolt locations.

The strap provides a critical part of your antenna installation, the ground plane. The more metal you have on for the ground side of your antenna the better it will perform. For lower frequencies this is particularly important. Sometimes gate or trunk hinges provide an inadequate connection, so the antenna performs poorly (high SWR, poor range, etc). The strap is bonding the metal of the gate to the tub, and anything welded or wired to the tub itself. I have more straps running from the hood to the firewall, the battery to the motor, exhaust to the frame, all in an effort to bond as much metal as possible. You don't need to go overboard, I'd say try the gate for now.

I get the strap at a local electronics specialty store, kinda expensive but the physical characteristics of ground straps vs wires provides a better connection. Keep in mind that this may not solve your problem at all. Things like a bad piece of coax or an antenna tuned to another vehicle can be just as much of a problem. Check these first, and at least a few times a year once installed.

With all of that in mind, I still would bond the gate even if I had a really low SWR, just good practice when installing radios operating on a lower frequency.
I basically followed your instructions to a "T" and my SWR dropped immediately to about a 1.2 or so. I knew everything else was done right since I've been using CBs since the 70s or 80s when The Bandit movies made CBs popular. Strange that I never had a problem before but I assume this was due to the spare tire mount location. I'm probably a little older than most guys on here (55) and I've had 6 or 7 Jeeps starting with my 2nd favorite, a '78 CJ5. My current (and last) 2013 Wrangler Sport is my favorite, hands down. Although you can't do as much to the engine like you could with the V8 that came in a CJ, my back doesn't really allow me to do physical labor anymore, anyway. But thanks again for your help. Just proves that no matter how many 4X4s you've owned (I guesstimate 15) you can always learn something new.

I have a 2014 Rubicon 2 door.

Hate to think of drilling holes in it, but,
If necessary, 1 or 2 may be ok, to mount
My Yeasu 2/440 mobile radio.

I'd love to see some pics of radios
In other JK's.

Next, antenna. Wife had a Comet brand
2/440 antenna mounted on a metal "L"
Bracket, that was screwed into top right
Side (2 holes) of spare tire carrier,
On her 09 JK 4 door.

After a couple Winters here in NE Ohio, the
Base rusted onto the bracket, and I destroyed
The base taking it off of the L bracket.
Not sure what I'm going to do on my new Rubi?

Default Here's where I mounted mine.

It's an Army Edition Cobra 29 LTD but I'm thinking about selling this CB for a different model.

I have this mount, which I got from Quadratec. No drilling, very solid, easy installation, and no loss of leg room. It's perfect for my Yaesu 2m. They make a smaller version for radios like the the Uniden 510/520, but this larger version will work for either.

Any idea how wide those spacers are? I'm asking because they look rather narrow. I don't want them to break or wear through the plastic with the vibration of the rig.
