The only bad part of being out tailgating all day is that we don't get to watch any other games that day and tend to miss a lot. So what's the best and/or easiest way to watch games outside?

If I get an HD antenna does that work pretty good out in the parking lots?

How does the satellite thing work? I've got DirecTV at home, but i'm not really interested in climbing up and taking it down every home game. Can i buy a dish off craigslist or something and take that with one of my home receivers and still use my account?
