Sounds as you are talking about video resolution e.g. number of lines. :mozilla_wink:
I wished I knew which satellites/transponders are on the border line where the larger dish would help. #-o

I used the term resolution because some of the equations I used to calculate it come from radio astronomy, where they are trying to resolve signals between 2 stars or something, which is analogous to resolving signals from two adjacent satellites.
Re predicting what signals you'd have problems with, I don't know, other than looking at Lyngsat. It's not that common, but I've seen problems a couple times on
C-band with my 10' dish, which is similar to the 3' dish on Ku. Had to move the dish slightly off center to get one channel to come in, because there was a signal on the adjacent sat with nearly the same parameters. You probably won't have any problem with most signals with the smaller dish, but it is another reason that bigger is better.
