I will be heading to a friend of mines house next weekend and he is wanting to put up a DirectTV 3-LNB dish on his barn to get television service out there. I can't seem to find the calculator anywhere for the angle/skew settings for the different dishes. I know I have seen it before when Installed my Dish 1000+. Was hoping you DirectTV folks could help me out with the information. His zip code is 62017. Also, I am not sure what reciever he is going to use. i have also not seen the dish personally yet. Is there any chance he is going to need a switch? Thanks for the info!
