Crafty little CB Antenna mount on a budget
I did this about 8 months ago, but never shared it. Still holding up strong!

I ended up getting a 5 ft Firestik Cut-to-tune antenna from a friend for $10 and needed a cheap way to mount it. Couldn't really mount it on the tire carrier because the antenna was so damn long. The only other option that I really liked was the CoolTech Ultramount, but $90 for an antenna mount? That cost more than my CB radio and antenna combined!

I still liked the concept of that mount tho, so I decided to copy it and save some cash. I started with a cheapo Firestik 3-way mount. Amazon sells them for $20, but I picked it up for about $15 at a local offroad shop.

Firestik 3-way Antenna Mount

Take the license plate off

Pop out the front plastic inside the license plate bracket

From here, you can see pretty much what I did. Drilled a hole in the top of the license plate holder big enough for the antenna after I'd lined up the antenna mount. Then drilled 4 holes in the forward side of the mount big enough for the bolts that I used. I don't remember the sizes, but you can eyeball it and be just fine. From there, I cut a length of some 14 ga. wire I had laying around and put some terminal lugs on the ends. Put one lug on a bolt for the antenna mount, and ran the wire down behind the mount underneath the body of the jeep. I drilled a hold big enough for a bolt in the frame, ground some paint off, and threw that bolt and terminal lug on. Now the mount is grounded and you're pretty much good to go. If I skipped any smaller steps, they should be self explanatory. There's lots of eyeballing and guesswork in this, so you can definitely make it your own. Any quesions, feel free to ask!

And here's a little cheat sheet for setting up the antenna properly on the mount. It was a few days before I found this and was wondering why my antenna wouldn't tune properly. Having your metal and plastic washers in the right order really helps out!

That's a really nice, clean set up! Nice job!

Not a bad setup. Might try it too. Would you get a good signal with it?

mattdenney07 04-02-2013 12:29 PM

Yeah it works great. With the 5 ft fire stick, I tuned it down to 1.2 really easily.

Doing this today. Best I have seen. But how do you run the wire into the cab?

Sorry for the late response. If you pull the carpet back in the aft left corner of your Jeep, there's a rubber grommet that has some wiring routed thru there. I just ran the coax cable thru there and down to the license plate bracket, then ran the rest of the cable under the carpet along the left side of the jeep all the way up to my radio. Took some finagling, but got it up behind the sun visors eventually.

Did you add any RTV or anything around the top hole to keep water out?

No, but I drill a couple small holes at the bottom of the license plate mount on the inside to let water drain out. It only rains a couple times a year in Vegas, so I wasn't too worried.

I like your antenna setup. I'm considering following your plans.

After having yours on for a while, do you see a need for a spring at the base to relieve some of the stress in the plastic license plate holder when you hit the antenna on something?

I think I may have to use a spring at the base just to get a 3 ft antenna slightly above my roofline. I can't use a 4 ft antenna if I want to park in my garage.

Wow! I am glad that this thread got pushed forward! This would be great for what I want! Thanks a bunch!!

Looks great and very crafty. I would recommend adding a spring to the antenna (like Hawaii 50 said).... you know you're gonna hit something sometime....:whistling:

Thank you Matt! I stole your idea today and it came out nice!
