We use DirectTV and have for ten years. We have the Winegard with the SWM setup. If you can get the HR54 receiver because it has the power inserter and the internet interface built in. Previous versions of the receiver required separate components for those two operations. The client boxes allow you to watch other TVs in other locations. One client box per additional TV.

So to get to what I think you really are asking. The receiver connects to the Winegard via standard coax cabling. The winegard requires a second connection cable for it's power and communication to the dish controller. The clients for the additional TVs talk to the receiver using coax cabling. To make this work in the coach or in a house, all the coax cables need to connect to a SWM splitter. It is easy to do this in the coach, you just have to sort through the jungle in the overhead console to see which coax goes to which TV.

We move the receiver and the client box from the house to the coach when we travel. It takes about two minutes per to hook them up. That way Rhonda has everything she has recorded at home to watch on the road.

If you will go to the trouble of setting up DNS (distant network services) with DirectTV you can get the network feeds from either the east or west coast, so that you don't lose network coverage when you travel outside of your home zone. It also helps if you record a lot of network serial TV shows to set up the recorder on the DNS feed so you don't have to reprogram the receiver when you travel. DNS is not a DirectTV gimmick, it is an FCC thing, so don't think Direct is trying to hassle you by having you fill out the form.

If you have Direct install a system at your house, all you need is the Winegard with SWM on the Newell. If you already have a Winegard, I think you can simply buy a SWM style LNB for the existing dish. Keeping in mind the SWM systems need a power inserter that the old school LNBs did not.

BTW, if you need a power inserter, I have three that are no longer in use. It's a long story.
