I'm still toying with the idea of doing similar, but not up to scratch yet with what gear to get or the lingo. How does the dish cater for the fact that Say B3, Pas8 and Pas2 are on different altitudes? The one that I was looking at (~$100) only rotated the dish, it didn't adjust the angle from horizon (decliantion?).

I'd need to replace my 65cm dish too as it's not quite good enough for the RT signal on B3 really...
