I'm using one in mid-Michigan, and I get nearly everything out there on C-band. In my case, at least 95%+ of what's possible. There's only a few signals I can't keep locked, but most of those are scrambled signals and unusable anyway.
I really recommend a 10 footer if your lot can accommodate one and there's one available to you, however if all you have is that 8 footer, it's worth putting up to try it. I recommend that you put a pole up tall enough and strong enough to eventually switch to a 10 footer though. That way you are covered in case you eventually decide to go larger.
P.s. It's NOT all that good at getting KU signals, with a dual C/Ku lnbf however.
