Question CB Antenna Mount Location

I'm looking to install a new cb system in my TJ but I was wondering which would be the best antenna mount location. I was debating between a hood mount and the TeraFlex rear light mount. I was leaning towards the hood mount but I was concerned about the radio interference from the engine and the difficulty of routing the coax through the firewall (I'm told there's pre-existing holes). Your thoughts?

You shouldnt have a problem running thru the firewall, i had to run my power wire for my amp thru the fire wall, so i found an existing grommet and put a hole and my wire thru that to give it the best seal

Antenna location wouldn't matter for engine noise through the CB. Engine noise is caused from how you have your CB wired for power. To make sure you don't get engine noise you should run the power wires directly to the battery. As for Antenna location, i would use the teraflex tail light mount. But be sure to scrap some paint off the tub so the mount would have a good ground. Avoid mounting the antenna to the rear tire carrier unless you plan on using a grounding strap from the tire carrier to the frame. The endgate or tire carrier doesn't offer a good enough ground for the antenna to work like it should. Some people get lucky, and get it to work, and some do not. And last ... be sure to check the SWRs on the antenna after you install it. This is very important if your gona have a decent operating CB.

Well to be honest the tire carrier should be the best or one of. The tire carrier is connected to the frame. Good enough for what I call a good ground.

I like the look of the tera flex mount better but the problem with that one is if you go led flush mount lights your teraflex adapter goes to ebay or the trashcan.

The tire carrier i was talking about is the one mounted to the endgate. The hinges and latch on the endgate doesn't give a good enough ground. Also if the tire carrier that you have mounted to the frame swings to open the endgate, then you still have the same problem as not having a good enough ground. You must have a good solid metal to metal contact for a good ground. Hinges have grease and rubber bushings to prevent a good solid ground, and the latch just does not give you enough metal to metal contact. But some have had success by mounting it there, others have not.

I am also looking for the right set-up, just found this at Quadratech....have not seen this set up before, is inexpensive, wonder how well it would work? Of coarse, you have to have tubular bumpers, which I do........

Thanks for all the help guys. I think I'm going to go with the hood mount just for ease of installation. If I can run it through the firewall, it'd be a shorter trip than having to run the coax all the way from the back of the rig (and it'd be cheaper too).

The Arizona rocky road antenna mount on the endgate is a very good idea. I have one of these but i kept having swr problems since i didn't have a good ground. Like i said the hinges and latch does not give you a good ground. I could have used a grounding strap from the endgate to the frame but i just decided to move my antenna to a side mount. I mounted it right above the rear tail light. I have a good ground and my swrs are perfect.

I dont run a ground on mine, no need to, the fellow at the CB shop DID inform me however, that with jeeps (especially soft tops) the extra hardware on it screws up the RF, so i had to get a custom made Coax harness. been fine ever since....

I have been keeping this idea in the back of my mind for future, and I like the look of this set up.
