I am currently a Dish Network 200 subscriber. I have a Dish 500 with a dual LNB. I have two receiver boxes. I want to add an International channel but am not sure if I need a bigger dish or a different LNB. I know that the international programing comes from a different satellite. I have an addt'l Dish 500 dish with a dual LNB. Can I use it to receive the internatiol channel that I want to subscribe?
