If you set the actuator arm right, it should be able to get most of the arc. Bigger dish like a 10' might need a 24" actuator to do it better. Right now I got a cheap 18" on a 10'Sami and its only going from 137 to 87, but I adjusted it so I could get 137 for the Alaska hockey games and NASA. If you want S2, there's supposed to be a ton of RTV channels on AMC3 Cband. Right now a good variety of stuff on G17 @91 c-band.
