Because of obstructions we're unable to see the right combination of DISH satellites to get all the channels (particularly HD ones) that we're paying for. I need to look at DirecTV as an alternative, and I don't understand which satellites DirecTV uses. TheList only shows three: 101W, 110W, and 119W. Do those three birds carry all of the DirecTV channels for ConUS? What about local channels, which I assume are spotbeams from some satellite. We're in the Houston, TX market. Would appreciate any background or links to other resources with such information. I'm asking because I want to use my DishPointer AR Pro app to see if clearance is any better with DirecTV than Dish.
