Yes I understand what you want and the best way is let DirecTV do it. There are a few things that need to be used like solid copper core RG6 from the equipment room to the dish and that could be up to 4 lines depending on what is need to met what your requirements are. The cable runes from the rack to each location needs just one line in and DerecTV has a great deal of equipment to put together there systems. They also have what they call DECA that part of it and cares the network signal on the RG6, and that includes the whole home setup. I am not sure but I also believe that solid copper core RG6 is need there to. Run all the Cat5 and 6 you want for other things like smart TV's, computers and so forth, and the DirecTV is add ti your home net work with a cat5 to the router. Get them in there before the dry wall goes up or get a list of what is need from them and have your contractor do the cable runs with the rest of it, and after you are there have them install the rest of you system. One more thing to make sure of, all cables need to be home runs from your equipment room to the location in the home or the satellite dish. NO splitters
The 4x4 matrix is for something ells, not for cable/satellite systems. Maybe for an HDMI system from a blue ray player to TV's all over the house, and if thats what you are thinking its not going to workout well and you are better of having the players with the sets that play them.
This is a forum for satellite TV, DirecTV and Dish.
and this web site has the equipment for both systems to help you become aware of what is need for your install.
