I also had a dome on the roof that was out of date. We decided to get the portable X2 automatic and we are very happy with it. There have been a number of times where a roof mounted dish would have been blocked by trees and we were able to get the signal with the X2. The X2 supports 2 receivers but we only use one. We have an HDMI cable front the front of the coach to the back and have an HDMI splitter in the front of the coach so the HDMI signal out of the received goes to the front and back TV. We have been very happy with the X2.
