On my Jku I installed a Uniden pro 510xl on the driver side of the gear selector. Since it's a compact unit it fits really nice. Then I mounted the mic just behind the windshield washer switch on the dash. Really easy to reach. I did a lot of research on mounts and found a mount by CoolTech. It is an antenna mount on the license plate. Puts the antenna in the open. I love the location and I get a decent swr about 1.5:1-1.7:1.
Antenna wise I started with a firestik firefly 4' which is now my trail antenna since it is so flexible. I wanted to try other antennas out and see what was the best. I really wanted a stout antenna for highway use. So I ran out and got a Wilson fiberglass 4' and couldn't get it tuned well and wasn't receiving the best. Definitely wasn't reaching out either. So ran back to the truck stop and got a K40 fiberglass 4' and that thing tuned in great, crisp reception, and got out pretty good.
Recently did a night run and forgot to switch antennas. That K40 got beat to death on trees and my hard top. Didn't even flinch. Held up great! Mount stayed intact and never loosened up either. Very happy with my setup!
Here it is with the K40 after the night run.
Different angle but this is with the firestik.
