I used tie straps to mount it to the roll bar. I'll take some better pics and post them tomorrow. Just buy two four foot sections of shelving mounts at Home Depot, tie them together with zip ties and mount your CB radio to it. Then set the mount on top of your side roll bar and you're finished. Then just run the wires down the windshield.
CB radios draw very little power so when I hung mine, I ran the hot and ground to the sound bar and tapped into the dome light hot. I just put a
2 1/2 amp fin line use in the cb radio hot behind the dome light housing.
