I'm thinking of switching to Dish Network. I spoke to a rep at Dish and was told for my setup, (5 HDTV's), I'd need 2 Hoppers and 3 Joeys. My question is, can I take that second Hopper with me when I go camping and hook it up to another Dish Network satellite dish so I can have satellite TV while I am on the road? I already know that they make a specific unit for doing this but I am only asking about the Hopper. If I can do this, is the a particular satellite dish that I'd need to purchase? Thanks.
