I just purchased an antennae and power booster from alternativewireless.com and all I can say is I CAN HEAR YOU NOW!!!!! It is truelly amazing, living in an area with some hills and dead zone, where I have had total signal loss, I now have full bars. Yes it costs a few bucks, but I use the phone all day for business and when I travel to remote locations, this will cure the signal loss, when rving. For the TV I am using a maganetic mount this way I can switch cars with my beautiful wife, but for the TT, I mounted a Wilson Trucker up on the batwing. I needed the trucker as the roof is rubber and offered no ground plane. This way when I set up, crank up the batwing and full bars it is. Once less thing to be frustrated about when traveling.
Happy Trails.
