It does real good but some of the S2 are touchy...I think I get all of them that other people get but you have to be spot on to do it. They say if you can, get a 10', but 8' I hear is pretty good. Point is...don't chance it...those S2 HD channels are a pain.
I haven't dealt with sponsors on dishes. I have another 7.5 in the shed. Had two of them gave to me years ago. Would like to find a good 10' and put that up along with my 7.5 since my neighbors cut their tree down.
I have heard the 6' solid dishes are real good. No signal passes through at all!
You should look around before you buy one. You just might find a freebie...post on CL and here for one. Can't hurt.
