For home you will likely get a Genie either an HR44 or HR54 and wireless mini Genie for each TV after the first one. Simple solution is to not worry about it, rewire your RV to accommodate the Genie. This means possibly a new dish capable of receiving HD using SWM technology and making sure you have a good coax from outside to the back of the receiver. Along with the setup you get a power sully and splitter. From the splitter you run one signal to the back of the Genie and a second signal to the video bridge. The video bridge send a wireless signal to the mini Genie, so all you need there is a HDMI cable from the mini to the back of the TV and a 120VAC output. IF your roof top dish is not capable of getting Direct HD, you have a couple of choices. replace it with a Winegard Travler or buy from one of the on line resellers a complete package for around 200 dollars.
