I had mine professionally installed by a local shop who works on "a lot" of the local Jeeps here in CO. They said they have really great luck with installing it on the dash though I may experience some issues in some of the canyons. Well, after traveling/playing all around the Foothills and Rockies this Summer, I have experienced only a couple of canyons that 'steal' my signal. It only lasts a second though (unless Stella would be stopped in the dead zone, of course *has yet to happen*) and then the signal is back. For me, the antenna being mounted on the dash (and out of any risk of unexpected rain, intense CO sun, me forgetting something, etc) is perfect. I have the Bluetooth option, too, with the phone mic attached to the steering column, and have yet to drop a call. Maybe mine isn't perfect because of the canyon dead zones but it's 99.9% perfect! I wonder if I would lose those same signals (in really deep canyons) even if it was on the roll cage? I'm perfectly happy with my setup, regardless. All spring/summer/fall and MAYBE I've lost a total of 15sec.???? :thumb:
