HAM/CB Antenna Mounting on JKU - What works?

I'm a newbie when it comes to Jeeps, and to HAM radio for that matter. Recently got a 2014 JKU sport and am looking to install a dual band mobile radio. My biggest question is where to put the antenna? I've read all kinds of posts on various forums, and get a wide range of answers; from easiest install to best performance location (sorry, just not going to stick an antenna in the center of my hood). What I would like to have is a professional / factory looking antenna install that performs well - like it belongs on the jeep.

Would like to get some advice, suggestions, examples, experiences, etc from those that have put antenna's on their rigs. What has and has not worked well?

Appreciate the help.

I'm thinking of putting in on the back tire mount?! I'm not sure either but that seems like the most likely place to put a CB antenna.

For performance thats about the worst possible spot for it. Convenient yes but bad for performance.

I used a Comet lip mount on the hood for my dual band antenna and bolted a mount to the tub on the right rear corner for my cb antenna.

The "easy button" is either of the Cooltech LLC mounts.
The groundplane isn't ideal and it won't work the best ---- but cb never works the best...

I used their license plate mount on my last JK and switched to a Wilson Silverload Flex antenna after breaking a couple of Firelite antennas on the trail. The mount itself is solid and the install looks factory-clean.

I think I'm going with their tailgate kit this time around though. Won't hit as many branches and shrubs.

If you really really really want something that works, get a K40 or other baseloaded antenna and mount it to the roof with a radial groundplane kit. It will look awful, hit trees and parking structures, but work great.

I just listen in on the CB so Performance is not quite an issue for me, but I do park in my Garage every night and don't want to have to remove anything, and wanted a no mess installation so I made my own mount for the rear tire carrier and put it there.

I recently installed my Icom 880H in my 14 JK 4 Door and had the same questions. Went back and forth for a couple of weeks trying to decide on what to do. There are a ton of posts about this and essentially decided to try the easiest approach first. Bear in mind that the Jeep is one of the worst vehicles to put a Ham radio in. But that is not to say it won't/can't work. It just means it's not the best vehicle.

At first, I looked at the lip mount on the front hood but I just didn't like it being that close nor did I like the way it looked. So I was leaning toward one of the spare tire mounts. But then I came across a thread where the person mounted a lip mount on the back tailgate (some mounts will rotate) to the right of the spare tire. This allowed for super easy access to the inside to run the antenna wire. Here is the mount I used (NMO version).

Diamond® Antenna ~ K400 Trunk/Hatchback Mount

My antenna is a Comet 2x4SR. I went with this one as it has gotten good reviews and was a little longer than the Diamond one I had previously used and sticks a few inches above the roof of the vehicle.

NCG Company::::::::::::::::::::::::::::::::::::::::::: :::::::::::::::::::::::::::::::::::

So far I have been running this setup for a couple of weeks with good results. My main repeater that I work is just a few miles way but I can hit several others that are 10-30+ miles away.

This is what I found works best, and not permanent.

Tried the spare tire deal, and couldn't hear my 50w radio 4-5 miles away. Shitty spot for sure.

So I used one of the a pillar light mounts from poison spyder. And WaaLaa!!

The CB antenna spare mount is good if you have a top loaded antenna like the Firestiks. I think HAM antennas are base loaded which means you need a clear line of sight. So sticking it between the top and spare is a bad idea. I have the spare mount with a 4' firestik and it works great for my CB. If I was to mount a HAM antenna I would want it on the brake light or rear bumper. So you get at least a clear line of sight on most sides. I have seen people put them on the front bumper and detach it when they aren't in use.

I bought one of these. It mounts on the tire carrier using existing holes. Been on there for a while and radio reception is real good (48" top loaded Firestick).

I have been working the same issue. The CB is going on the rear tire carrier (who cares about the range it is just for talking on the trail) and the 2 meter ham is going on the hood driver's side edge.

Take a picture of that hood mount when you're done please.

I've installed my Comet SBB2 inside the jeep. Since the roof is either fabric or fiberglass, I get excellent transmission and reception, and a swr under 1.1

Maybe because the antenna is at the same height as the tub, the tub is kind of a ground plane? Not perfect, but antenna placement is always a compromise anyway.

I made a bracket for it, and connected it with a female-female PL connector. The bracket is connected to an existing bolt securing the hard top, so no drilling is required, and no antenna on the outside, so it's a stealth install. I love it!

Edit: I forgot to mention but since I live in Canada, in winter we have plenty of salt on our roads, and the Jeep is shaped like a brick which means backdrafts on the rear window, which means salt. I was worried about corrosion of bracket, connector and antenna by placing my antenna there. I had a CB antenna attached to the tire carrier before, and the bracket and connector needed paint, grease, care and love way too often for my taste.

This is the one I used, I could have made my own but it was just so easy and I was already ordering an antenna and coax from them.

The best pic I could find.

Here is mine. It works great and it doesn't interfere with the hood being open either. The radio is mounted under the dash and the remote head unit is mounted above the rear view mirror. Very happy with the results.

^^^^^ this. Great product. Plus the tailgate is easy to route the cable through.

Just hit the "easy button", and the stuff showed up yesterday. So planning to do the install this weekend.
Seems like quality stuff, and really like the mic mount.
The kit came with a 4' Firestik Firefly, which is really light and flexible, like a fishing pole.

I picked up a 2' Firestik-II as well. Hoping it will work on the trail well enough, because it won't be taller than the roof. Also picked up an external speaker, since my hearing is not so good.
If it works well, I'll post it up. If it doesn't... this post never existed...

It will work; just take your time routing your coax, tune your antenna, etc. Don't "loop" the coax btw.

On my last Jeep I mounted an external speaker up above the rearview mirror and aimed it at my skull. Worked great and the wire was easy to route inside the plastic liner up there.
My new cb has a front-firing speaker and is much more intelligible at speed.

Thanks Bill,
Sincerely appreciate the input.
Got it all mounted up, and tuned both the 2' Firestik-II, and the 4' Firestik Firefly. The 2' tuned right about 1.2-1.3. The 4' tuned to about 1.3-1.4.
Going to check distance around town tonight.

The Cool Tech "all in one" kit with the Gate Mount worked out really nice. I added a heavy duty spring on the 4', and a medium spring on the 2'. Both antennas hit the spare tire a bit, so this keeps the stress off, and makes changing the antennas quick.
Here's a shot of the 2' Firestik.



I did a couple of things slightly different.
Added an aluminum plate to the Versa Mount, so that the Ham hand talkie has a place to ride. It's painted with bed liner, and on the hand talkie side, I coated it in non-skid paint as well.




Instead of using the plate and screws for the mic grommet, I just put it right in the lower dash panel.

Any of you using the rear tire mount picking up an humming "wind noise" on the antenna?

I've used the license plate location before with no issues. Using the rear tire mount with a 4' FS and picking up noticeable wind noise. Looking for ideas.

I have a thin steel antenna mounted on the TF bracket on the tire mount and the only time I get a whistle is about 60mph and it has to be damp/foggy out.

I mounted mine on the cowl, my wife's and my good friends are all mounted this way. All three of us have had good success with this location and it works great, although make sure you use a spring ..
