I will be moving this summer way out in the sticks and there is no cable so I will have to go Sat. I already have an HDTV antenna setup that works great but I want to add either Dish or Directv to the house. My question is, can I bring both the cables into a multiplexer and then bring the one cable in the house. I have a shop that is seperate from the house. It will have the dish and antenna mounted on it. I want to bring the single cable into the shop so I can watch tv and then run that cable on into the house to the other tv. Is this possible and what would I need?
