I know that Cal4Wheel and others require that your cb antenna length be no longer than about 4 feet. Has anyone heard about any restrictions with how high above your vehicle the antenna can be?
I just put in a new cb and had to relocate my antenna to get good SWR measurements. I've now got a 4' tall antenna mounted to the top of my trail rack. It sticks up about 3.5' above my Jeep. It looks a little tall, but it gets 1.3 on the SWR on every channel.

I think you'll be fine.
I worked trek staging for 4 years and we would only take issue with metal antennas that could fly all over the place. We had a few show up with 9 foot whip antennas that we made duct tape to the roll cage or remove entirely. fiberglass antenna's were not a problem no matter how high they were, and even 5 footers were overlooked.
Is it on a spring mount? Up that high it might get torn off in the trees if its not.

Thread semi-hijack. I tried to tune my CB, but have no clue what I'm doing-even after reading the directions. Could I run by some time and get a check up?

George lent me his and its in my garage. Still no clue...
I can show you how, but I'm heading to bed. I'll be around tomorrow evening if you still need some help.
Does the meter have instructions?
If its like mine you plug it in inline. Flip the switch to fwd, key the mike adjust a knob to get the max power then flip the switch to rev and read the SWR.
check on 1, 20 and 40.
If high on 1, lower on 20 and lower still on 40 the antenna needs to be lenghened slightly with the tuning screw.
If high on 40, lower on 20 and lowest on 1, try shortening antenna by screwing in the tuning screw slightly.
Make small changes.

caveat: this is from memory and I haven't done this in 10 years and can't find the instructions and haven't read the instructions in probably 25 years so I might have this mixed up.

OK, last one. I think my instructions are pretty close but here is a writeup.
