My sister has a 1000.2 dish pointed at the Western Arc, but our locals in HD for the Paducah, KY market are on the Eastern Arc 61.5* sat. If I were to purchase and install 1000.2 Easter Arc LNBF, would it work just by getting a signal lock, or would I need to contact DISH and let them know that I switched over? In other words, would DISH need to change any equipment authorizations or anything like that on their end?
