I mounted mine on my rear tire carrier using a stainless steel bracket I picked up from Quadratec.

I had a 3' firestick on my spare tire mount using a rugged ridge mount. When I lifted the jeep, the antenna started whacking things in the parking garage as well as my garage door at home. I went to a 2' firestick and lost my reception and transmission distance. I still have to park in garages at both ends of my commute, so I got rid of the CB radio all together. It was only good for listening to truckers cursing constantly and ads from truck stops about happy ending showers.

Magnetic mount. I stick it on the hood.

Thanks for the replies. For those of you mounting it behind the spare tire, are there any problems with the clearance from the tire?

Depends on the tire... Stock size is no problem.

I'm using 285/70R17 Duratracs. The wider tire does press against the antenna which causes it to tilt forward slightly. It's not really a bad thing electrically since rubber is an insulator. Doesn't affect SWR.

But to eliminate the tilt and make things neater, I put a couple of washers on the top two spare tire hold down studs. this tilts the tire back a bit letting the antenna go back to vertical.

Same one I use. With the 315's the Smittybilt tire carrier has to be fully extended to clear, but it works as expected.

Be sure to clean off the paint where the bolts go through the mount to get any kind of ground for the antenna.
A good weaved ground strap will always be best, but with the paint intact on that mount you have zero chance of any kind of ground.
Thats why I went with the stainless mount, no paint at all to worry about.

Nothing wrong with a happy ending anything!?!

I too have the same set up but a 4’ fire stick. Yep it hits stuff but not that big a deal so far. CB works great and it fits like a glove between the spare & gate. I also removed the powder coat from the area that touches the tailgate for a good ground otherwise you will struggle with the SWR’s.

Thanks for all the replies! I picked up a stainless one today. I'll put it on over the weekend.

Had a poison Spyder mount on the driver's side of spare tire. That eliminated the problem of hit the glass when opening or closing. (3' firestik) but couldn't get set below 3:1 no matter the adjustment to the firestik. Moved it to the license plate, put the adjuster back to where I started. SWR was 1.1:1 without adjustment. There is more to mounting that antenna than where it is out of the way and looks good. Other jeepers on the trail say I'm the only one they have to turn the volume down for. To hear anyone else volume is all the way up.

I'll throw this out there.
I mounted our CB antenna to the front bumper (a metal front bumper. It is a 4" Firestick mounted to the front bumper. It is not in the way opening the rear window, and it is where I can see it. And it isn't as bad catching on overhanging trees and what not, plus if it does catch on something and starts swinging back and forth there is nothing for it to hit.
I was going to mount it to the rear tire carrier, but a more experienced off road guy suggested the unorthodox mounting location and it seems to work well.

Using some basic antenna image theory, the best spot on a jeep should be the middle of the hood. Good ground plane.

Oh, another advantage to the front bumper mounting, beyond that the front bumper is a great ground, was that it was easy to run the antenna wire from the front of the cab under the dash to the front bumper. Just run the wire through one of the existing grommet holes in the firewall and over to the front bumper. Easy. No worries about getting it under the carpet, no worries about getting it through the hinge area for the rear door.

And with careful positioning you can use it as a sight for the RF wheel tracking.

Plus front bumper mounts look cool.. Here's a Telecom 9300 on a JK. It's designed for the ham and commercial HF bands, but will work just fine for CB. Only problem is that it costs over $2500.00

Get yourself some 550 cord make a short loop at the top of the antenna. Tie a longer one from the side of the bumper. I tied on to my highlift jack. Bend antenna and tie or use a small clip to fasten loop to longer piece.

Antenna now no longer hits garage door still works for a shorter range. Un-clip when you need max range.

Military ties down antennas all the time shut keep the bend small just enough to clear the door otherwise it sticks out to far to the side of the vehicle. If correct it won't stick out at all.

Nice looking antenna! Less expensive screwdriver HF options like Hi-Q and Tarheel.

On the hood. It is the best location on the Jeep from RF perspective. A CB antenna needs a ground plane - a large, preferably horizontal piece of metal. Mounting it on the tire carrier does not really provide one.
In addition this location more reliable, as the cable doesn't bend when opening and closing the tailgate. It also simplifies the wiring. The antenna cable can go straight through one of the rubber stubs in the firewall to the cabin.

P.S. Initially I had my antenna mounted on the tire carrier, but fairly quickly the cable got destroyed, despite that I've attached it to the wire harness going to the tailgate.

MAN!!!!! You opened a big enough can of worms that we can all go fishing!

Qualifications: Licensed ham op since 1978, Extra Class. Military commo experience (not primary job), presently electronics/electrical professional.

Rule #1 - the antenna is everything. Rule #2 - Read rule #1 again.

Example: A $20,000 Hilberling PT-8000 radio using a damp spaghetti noodle for an antenna would be hopeless. But a $50 CB radio on a decent antenna is going to get the job done.

The most efficient antenna for CB is a 108 inch (9 ft) whip. They are big, often difficult to deal with. But that would be the "best" solution.

Once an antenna gets below 3/8 of the optimum size, it starts to give up efficiency rapidly. So best look at antenna in the 4 ft range or greater if possible.

Optimum mounting point is as high up as possible under a good ground plane. Very hard to do with a soft top or a hard top. Pretty easy if you have no top and will not put a top on it. I'm getting to be an old fart, I like my heater in the winter and my A/C in the summer. So other options were necessary. Also, since CB is not my primary communications system (Ham V/UHF is), I was less concerned with optimum placement of the antenna.

Because space for mounting in my vehicle is at a premium, I found this kit and it was EXACTLY what I wanted. GOOD radio, ACCEPTABLE antenna, reasonable mounting point.

For a couple of photos on the install of my JKU-R-Hard Rock, go to my profile page here: http://www.qrz.com/db/kd5kc/

If I can help you in any way, just give a yell. Always willing to help someone get it done right. It's the ones who ask questions that get good results. I hate the ones that "know it all" because when their crappy install don't work they get pissed when you try to help them. They eventually figure it out when nobody answers them! <grin>.

Wishing you the very best of luck sir.

Used a TJ Mirror Mount

I used an extra TJ mirror mount and welded a piece of 3/4 inch tubing to the side to beef it up. Then I mounted it on the right rear quarter next to the curve for maximum strength. I put a backer on it to make sure it didn't flex my steel.


I've got a 4 foot FireStick whip with a heavy-duty spring on it and it stays nice and straight even at highway speeds.

It fits like this:

I used the same antenna mount for my 4' firestik, but because I'm running 35's i couldn't mount it on the corner the instructions tell you to mount it. Instead I mounted it in the lower left corner. Works perfectly fine but sits about 6" lower.

Mine is part of the rear lic plate holder, mount is under the plastic. Looks cool, nothing showing. Antenna is stored with velcro on the roll bar inside. Cobra CB is hard wired inside the center console. Out of sight is out of mind.

I find I use GMRS (handheld 2-way radios) more that CBs on the trails. I set my Jeep up for both. With GMRS, I can hand someone I meet along the trail a spare 2-way radio so we can travel together and stay in communication. I have CB for organized trail rides but even those most do not have CBs but do have GMRS. I made my own antenna mount to hold both antennas. It holds the antennas higher than the one shown in previous posts. I also made my own CB/GMRS radio mic mount. It holds the mic higher on the dash than the commercially made ones.

I used a 4" long piece of 1"x 1" aluminum angle Iron screwed to back of the 3rd brake light.
