I couldn't tell you...Because after hooking it up, testing for ground and continuity, and tuning the antennae-tip, I drove it by my local truckstop and asked the mechanic to give it an SWR-reading. He did this for free, and it only took a few minutes. He told me it couldn't be any better and asked me who hooked-up everything because they had done a great job...

 

I am about to mount mine like you have yours. It seemed like it was going to wack the 3rd brake light, any hitting from bouncing around, thanks for any reply

 

Mine hit a little, when wheeling, but I found a rubber bushing that fit over the antennae and I slid it down to sit against the side of the brakelight. That kept it from bouncing around and hitting or making any noise over bumps.

 

Excellent idea! You just saved me $40+

 

Drill a hole in a Tennis Ball and put on your CB Antenna, worked for me. Papabear

 

I think he makes some good points about cost and positioning, to which I stand corrected. However, I think there are still many circumstances where that location would be a bad one - but he's right in the fact that if you're that kind of trail rider, you should know better than to mount there.

At this point I'm still planning on going the DIY route, but I think its worth mentioning that CoolTech stands behind his product so much he's sending me a left over pre-production demo unit (bracket only) for my evaluation.

I think that's a pretty stand-up move and a testimate to the good nature of this forum as well as the jeep community as a whole.

 

FWIW, I received most of my antenna install items last night but was shorted the fire ring stud mount . That's on the way now, so I was left to ground my tailgate. I used a 12" braided strap and bolted it so it is located behind the existing nylon wire cover. It came out better than I expected, both asthetically and electrically, measured .003Ω from body to gate I'll post up some pics when I do the full antenna install.

 

Man...you are not kidding! I couldn't get an 18ft to reach where I needed it!:sad:

 

The recommended length for coax is 18 feet. If you cannot use 18 feet, you can use a minimum of 9 feet with increments of 3 feet (example: 9, 12, 15, 18, 21, 24, 27). Be careful of what you do with your excess cable. If you need to wrap it, let it hang loose and carefully wrap it in a 12 to 16 inch circle (elbow to hand roll), wire tire it in the center, and put it out of sight under your seat or dash. Failure to do so could result in a RF choke.

 

I like the mount on the spare tire and that's what I had on my TJ. On my JK, though I have a swing away tire, I didn't want to drill in it, so I slapped on the Ultra mount. I love it, never had it hit anything, and it works great on the trail, no issue with it hitting. The only times I've had anything hit is when going under a low tree (as in branches rubbing across my top).
