If you connect the receiver, go to Setup and when you get to the Satellite Dish setup, it tells you the azimuth, elevation and tilt. If you know the azimuth, you can use a compass to determine the best place. That way, it doesn't need to be repeated.
OTOH, if the posts are in the right place, you could always put up a volleyball net or a hammock.
What they get is determined by what they can pay and they can't pay much. Dish isn't always much better- tehy have some of teh worst CS people I have dealt with and yesterday was a shining example of how NOT to do business. DirecTV now uses Dish satellites, since Delphi closed and since Delphi owned Hughes, they (DirecTV) had to suck it up and do what they can to get people to sign up with them. I have had Time Warner Cable and now I have DirecTV. Time Warner is pure evil and overall, I'm happy with DirecTV. The picture quality and sound are better then Time Warner and I like the XM music. I'm not happy about hte Sirius channels that replaced some of the XM channels that were dumped. I liked some of them a lot.
