Last week we tried for the first time to set up our Dish Network at out tailgate in Ann Arbor, MI. We have an oval dish (friend of mine) with a single LNB and my second receiver from my home. We had signals at my house and another location as we tried this out prior to the tailgate. At the tailgat we got ESPN but no locals. Called Dish and they tried to help but couldn't. Then we lost ESPN and couldn't watch anything. I NEED HELP. Do I need a Dual LNB? Also, with a single LNB do I run one cable to the reciever split into both satellite feeds, or two from LNB directly into both satellite feeds on the reciever? Or is there something else I'm missing. Please help the next game is Saturday!
