CB antenna mounting location

Is anyone using a firestik or wilson tunable cb antenna mounted on their rear tire carrier? Any issue with the grounding? I want to install it on mine but not sure if the tire carrier will provide sufficient grounding. Pics will help...thanks.

3' Wilson or 3' firestik tunable antenna?

Im thinking of putting mine there. There is a pretty good write up in this months issue of JP mag. about cb and antenna installation. You can read it online.

I don't have one but if I get one I plan to mount it identical to the stock radio antenna just on the other side. I haven't seen many done this way...

That is a good idea also. Mine is constantly whipping my roof rack and annoyed the crap out of me so I zip tied it to my roof rack support post. This may happen to me if I mount the cb antenna there also.

I can't seem to find that article in JP. Do you by any chance have the link to it?

Thanks

It won't have enough grounding by itself. I have a 5' (6'?) Wilson there, which works great, except in parking structures and at the drive-thru carwash. I ran a separate ground wire back from the mount into the vehicle and grounded to the a rear seat bracket bolt on the fenderwell. All my wires run through the grommet where the third brakelight wires used to run, back before the third brakelight went in the shitcan.

I was wondering if anybody is running the flush mount 4" LEDs and where they have their CB antenna mounted. I was planning on buying the Teraflex antenna mount that goes behind the driver side taillight but I have been contemplating going to the flush-mounts so I was wondering where people who had them mounted their CB antenna?

i say keep it on the tailgate. that way you'll need less wire and less chance of pinching the wire.

heres what i did:

With this mount the wire is connected on the other side and it don't have to be grounded.

Do you have a picture of the separate ground wire? I might have to do this and not sure how it is done.

Thanks

i mounted my antena on the front fender, gounded it to the frame. but i have a wilson K2500 (whip) (i think its what it is...lol) i didnt want a fiberglass antena as i think they would break easier, and didnt want to have it stuck in the back because of the reception.


correction, its a 2000.

If you run a separate ground, it can't be a small wire. A ground strap is recommended (braided). I made a copy of the mount that goes behind the light and ran a braided strap through a grommet in the tail light husing to a mount nut for the light. It was already grounded, but that was to make sure it was a good one.

I believe the lower lug is where you connect the ground to. Its true that this is a NGP antenna, but that is different than a ground. An NGP antenna kit like this one is good for a Wrangler type vehicle. Your rf signal goes straight down til it hits the ground plane. Then it emits out in the direction of the plane. On the rear of the vehicle, you will get a better signal going forward than back because there is no ground plane behind the antenna. One of these NGP antennas eliminates the need for a ground plane. You can also eliminate the need for a ground plane by using two antennas. that pic up there with the two antenna mount on the tailgate is wrong, though. You don't want them to be that close together. When you have two antennas, the signal goes more front and back, unlike one antenna where it goes 360 degrees.

I used a piece of 1"x4"x1/8" stainless steel to mount my first CB antenna to the spare tire carrier. The spare tire mounting surface it mounts to slopes downward slightly so I simply gave the stainless steel a slight twist so the antenna would be vertical.

Jerry~ did it provide sufficient amount of grounding or you have to install a separate grounding wire? I am mounting mine to a Body Armor swing out tire carrier which has an antenna mount already. I am not sure if this will work.

Thanks-Chio

What if your tail gate works Like the CJ's not the swing type like the TJ's then we gotta mount to the body.

Has anybody ever tried mounting the antenna bracket on the side of the tub, like right above/in front of the gas cap? I'm installing a dual antenna setup, but really don't want to have to pull the antennas off whenever I want to put my hard top back on. I was thinking about drilling through the side of the tub, but haven't seen anybody else do it that way...

If you offroad, having the antenna on the side of the Jeep would make the antenna highly vulnerable to being damaged.

Okay, what about cons/benefits for having them mounted:
a. right above the taillights
or
b. within a foot of each other, mounted on the stock tire carrier

I'm trying to squeeze as much signal as I can out of my setup (twin 4' Firestiks running into a Uniden 538W).

I had problems mounting it there; it could have been the way I wired it, something specific about my Jeep, who knows, but I got terrible interference from the engine when I mounted it there. I ended up getting a teraflex mount for behind my taillight. All is good now. I know several people who have them mounted on their tire carriers will good results as well.

I'm using tub mounted on the sides with a ball mount. I have one on each side. They do not stick out past the flairs. All antennas are attached with quick disconnects, so I can change what I am doing easily. The one in the picture is too tall for trail use. That's a Hustler CGT-144. Over 7' by itself, it works well but it hits stuff overhead. (I'ts also 2M not CB). Point is, I think a body mount is fine. It's strong, no question on ground bonding. It could get snagged, and just grit your teeth when you break out the hole saw.

I have two, if you only do one, put it on the drivers side, you have more overhead clearance towards the middle of the trail if you are riding on the right side.

I mounted a single tunable fiberglass antenna on the passenger side of my YJ tub, haven't had issues with trail damage yet.

Option A
There are no benefits to this at all, only cons. Dual antennas should be not be that close to each other. They should be 9 feet apart. Anything closer and it starts driving up the SWR to the point that a single antenna (with a lower swr) would have better range.



Option B
You are going to smoke the radio.


If you want the best range for your unit get a longer better antenna (single) choose a way to increase the power output.

X2 on Scoob's advice that twin antennas won't work on a Jeep. Plus you lose the omni-directionality of a single antenna and make it directional so it only transmits well fore and aft but not to the sides.

A single antenna is fine and works well for a Jeep. I've been doing 2-way radios since the sixties and simple is normally better.

I have the exact same Jeep as you. I have my antenna same side but behind the wheel well. Up here in Maine we need every bit of antenna performance we can get due to the distances.
