Just had to respond to this thread-
I can't recall how many times I got bored and decided just to tweak my dish. Why not it was a fine sunny day! By the time you get a small TV set out to the dish, the reciever and pull an extension cord accross the yard- that's half the effort. Once everything was ready for testing you hate to just spend 10 minutes testing and tweaking, before you know it your out there for an hour or two roasting in the sun.
Why didn't I ever think of this before, only takes a few minutes more to set up a sun shade! Really love your idea!!!! And you don't have to be in the deep south to enjoy it, do you supose Sunsetter Retractable Awnings are thinking about this?
