Most have satellite service at home, then find an extra dish at e-bay or a flea market, etc. Get roll of coaxial cable at walmart, etc. Take a control box from home when you go. Set up dish on a tripod of some sort, Here's mine
. Locate the satellites with the dish and "bingo" you are watching TV. The last part (locate the satellites) is the trickiest part, but with a little practice and research on these forums it gets easier.. Take me about 10 minutes on a bad day and 5 minutes on a good day. Good luck and welcome aboard.
