You could get 24" dish kit for the 110 and that should improve the signal if you are already getting some signal.
Just to make sure this isn't a misaligned dish 500, go to menu 6,1,1 and set the satellite to 110 and the transponder to 15 as well as 16, report your signal levels for both here. If those are weak, then the dish may just need re-alignment. but if they are good and your spotbeam for your locals is low, then you might be in a fringe area and a larger dish for the 110 might cure your issue.
