The Jeep and Offroad kit I got from rightchannelradios.com
is a really great kit. I upgraded to the Teraflex antenna mount that installs between the tail light and the body. The kit comes with everything you need, including an SWR meter, so antenna tuning was easy.
I mounted the radio overhead using a metal shelf support based on a write-up I found on JF. I chose to mount it overhead to get it out of the way, and so the speaker is well positioned. The Uniden has a pretty good output on the speaker, so it's relatively easy to hear.
I've had the radio for a couple months, and have used it on a couple of road trips and on the trail. The range seems to be pretty good, but that's mainly due to proper antenna tuning.
Overall, it's a great little compact radio, so mounting it anywhere is pretty easy. Reception and transmission are good, and the kit from rightchannelradios.com is a complete and service was great.
