I am adding a TV to my work office, which is in a seperate building 100 feet from my house or so. There is a 2 LNB satallite dish from Dish Network all set up down there from the previous owner from the shed. Would that work to pick up Directv channels with an allignment, or do I have to buy a brand new Directv dish? Directv tells me that they would need to charge for the new equipment since it is a seperate building. I can install everything myself but just want to check to see if I can save some money. It won't be HD down there right now anyway, just the SD channels (SD DVR).
