Antenna height

Just purchased my first cb setup just for trail riding (1mile radius or under) and I picked up a uniden pro505xl and a 3' firestik 2 and aluminum l shaped mount with heavy duty spring and 18' of rg58a/u coax. I don't have a fith wheel or stock tailights so the other brackets won't work. How high if at all should the antenna stick up above my soft top. I was hoping it would be none but seems I won't get any range if its not. originally I wanted it mounted on my bumper. Also I heard its better to mount it on the drivers side then passenger side. Any truth to that? Thanks for helping out a cb newb lol. Here's the rear of my jeep

Pretty much any place you can think of on the Wrangler is fine (except, of course, the top itself) as long as you understand that the antenna needs a 'ground plane' in order to operate as efficiently as possible. That said, most of us only use our CBs on the trail and very few other times so that issue and how it affects your TX/RX becomes a moot point.

Still, having the right ground plane (which Wranglers don't) will affect the SWR and how long your radio will live. Good thing Firestik makes a no ground plane antenna!

Regardless of what you may have heard, driver's side, passenger side, front, rear; it makes no difference as long as you understand that it will get smacked around by trees and such and that's where a sturdy spring and tennis ball comes in to play!

Thanks for the info. So your saying if I mount it to the rear bumper it should pick up fine.

Of course Wranglers have a good ground plane Mr Mac. If they didn't we'd all be using NGP (no ground plane) antennas which there is no need for. When the antenna and its mount are properly installed, the entire Jeep including its steel tub & frame combine to serve as a very good ground plane system for a CB or ham radio antenna.

Jaxon, your antenna doesn't have to extend above the soft top to work well. While the taller the antenna the better it works rule is true, even a 2' antenna mounted at tail light height like I run works very well when properly mounted and tuned for minimum SWR.

I've been involved with ham, cb, commercial, and military 2-way radios since the 60's so this isn't a subject I am unfamiliar with.

One other thing. The uniden I picked out has a 3.5mm jack for and external speaker. Can I just run a cable with two 3.5mm male ends into the aux of my radio and use that aswell?
