Someone pointed out that, for some G1 transponders, I might b e able to get with a better quality LNB. I thought that the only options for someone using an antenna, other than one provided by Shaw would have to either use the F1 X TWIN from KUSAT, Shaw Direct, Offset F1X LNBF [XKUF1] at Kusat.com or take the one from Shaw, remove the plastic casing , and then fastening it to the bracket of the dish. After talking to a commercial grade dealer, he explained that, if I were to have a PLL LNB, that my reception issue could be either solved or improved upon. The one that gets both F1 and G1 from Norsat is $2,000. However, they do have one , Norsat 4508C, that Shaw says will work http://www.shawbroadcast.com/Documents/Norsat_4508C_LNB_Technical_Spec_Sheet.pdf only has one output and only receives G1. Is there any way that I could set up something that would work with a 4580BC?
