With a really good 8.5 footer, that's well aligned, you'll get some S2. If it's a really great dish,like my birdview, you might be able to most of the s2 signals. However, those who say they get "all" of the s2 signals on an 8.5 foot dish, probably don't really know what "all" means, because there are some signals (8psk, 16apsk) that will be very problematic on a dish that size. I know because as I said, I have an 8.5' birdview. It's a great dish and I can get most of the signals I'm interested in with it, but there are occasionally times when I wish I had something bigger.
