My DCII stuff is on a 7.5 foot dish. It has a GeosatPro C2 dual output LNBF on it. Carefully tuned, I get a quality reading of 25-30 on the 920. If I remember it right, the 920's meter will show clear signal at lower numbers than a 922. Sometimes I still have to "nudge" the dish a click or 2, to get NET to play, but they do pretty good on my setup.
