My question is this: My parents have a Dish 500 and already have 2 lines for their 2 receivers soming into the house. Now they want to add a third receiver (which they have already acquired). Can they just use a Y splitter off one of the cables running into the house or will they need a speacial type of splitter? I know they will need to call Dish to report the receiver # and the new card number. Will they need to add a 3rd dish to the top of the house? Thanks ------------------ You've never worked in the private sector. They expect results.
