I'd mount it on the back but that is so it's not sticking up in front of my face.

Although I'm not a fan of the front mount attennas a 3' fire stick is to short to mount on the rear door. You need at least 2/3rd's of the anttenna to stick above the roof line for it to be effective.
Will this matter on the trail? Maybe not, depends on where you wheel. Stick it on the bumper or get a longer anttenna.

The Firsetick requires a ground plane. So it really should not be mounted in either of the places you mention. At least on the front bar you will get half the plane that you need off the hood. Still mount be all that effective. Get a shorter antenna and mount it as close as possible to the centre of your roof. Use a ski bar and mount it as close to the roof as possible. Otherwise spend a little more money and get an antenna that doesn't require a ground plane.

I mounted to the rear tire carrier on mine. It wasn't the perfect solution, obviously - but it worked better than I had expected. Decent reception on the highway, but bunched up in groups on trails there were no problems.
I ran the cable from the back door under the plastic on the side of the storage space, under the carpet beneath the rear seat up into the centre cubby bin between the front seats. I used a Cobra 75 WX/ST so it just had the little box to mount.

It's all about compromise when you're mounting a CB antenna on a trail rig.
As Ian says, the firestick, and actually all vertical antenna require a counterpoise (ground plane) beneath it, and the ideal situation, for omnidirectional capability, is directly in the center of a metal roof. For the obvious reasons, most people don't want it there. It often requires a hole in the roof, and leading in coax up inside the headliner. Even mounted to a roof bar, people don't want the antenna up there because of branches on the trail, garage doors, and lots of other reasons. Though not optimum, base loaded antennas work reasonably well on the front fender much better than on the rear spare mount, just because on the rear tire, it's so close to the body of the car, it significantly skews the radiation pattern. As long as the coil is above the hoodline when mounted on the brush bar, thats only marginally worse than the fender, but better than the rear tire mount. Where ever it gets stuck, remember to grond the coax at the mount end also, either through the mount, or with a pigtail. Otherwise, the coax becomes an active element. All 'short' antennas, firesticks, based loaded coils, etc, are inferior to a true quarter wave, 110" whip ( a real tree whipper on a trail rig) |
