Had an older inmotion roof mounted antenna and rarely used it. Between trees, mountains and other obstructions drop signal was pretty common when going down the road. Also since most of our outings are in forested state parks the static mounting on the roof was blocked most of the time. Replaced it with a carry out Winegard. Being potable finding a hole for a clear line of site isn't difficult but antenna can only track one satellite at a time which limits my viewing options with two receivers. Also the dome antennas can not decode HD channels with Direct subscription service.
