That all depends on what you'd classify as '
decent'. Just take the time to put it together correctly. Getting the feed position tweaked right-on for peaked performance. It probably won't get it 'all' because of its characteristics (lower gain, wider beam-width) than a larger dish. <I don't get it 'all' for what I think is numerous reasons, week TP, out of the hottest part of footprint, etc.> ICE is using 6 ft dishes, and <i'd say> gets 90+% that others get with a 10ft. Many others are also using 6ft, 7.5 and 8-9 ft dishes.
In some recent threads, Some are having troubles with
EWTN on 133W with a 6, others report success. Also harder to get may be the S-2 transponders. What exactly you will or won't get is really impossible to say until you try.
Maybe mention what you're after, and those with a 6 can post their outcomes on those satellite & TP's.
