OP asked about the Tailgator. I must admit, since getting my Tailgator, I've started reading through these Sat aiming threads just so I can laugh at other people and their misfortunes.
After a year of using the Tailgator, I can find only two objections to the current design:
1. Before watching TV, you have to remember to put it outside.
2. Before driving off, you have to remember to put it away.
I understand that an open dish, properly aimed, will get better reception and be more robust against rainstorms, but the little Tailgator does a good job, and I just have to remember steps #1 and #2.
