Nothing much KU FTA on G4R, and a Universal is not really required for anything there. The only real benefit I have seen with a Universal LNBF is I can pick up Cubavision on the Pas 9 satellite (58w) (and a few feeds). Unless you get a real good Universal (Invacom) I would use a standard LNBF.
I don't think I can get farther east than 61.5 (My house is in the way)

A KU Universal LNBF just gives you a wider scanning range of the KU band. C-band requires the VERY large 8-10' dish....
Sorry if you know all this stuff already
Well, I had to give up 8' Winegard/ Drake IRD C/Ku setup when we sold our old house

- So yah, I do know some of it!. But I obviously don't know it all!. Currently using a 1M Winegard/ SG 2100 HH motor / Pansat 2500A and get the arc from 61.5 to 127.0. Great hobby!
