you can use one lnb,set the skew at 0 and receive sat 61.5 which has all programing in SD,If you want HD aim at sat 72.7.on this sat is all HD programing except local networks.For coordinates go to aim dish screen an for dish type put in dish 300 and sat 61.5,now to find 72.7 it is about 5degrees higher and 7 degrees to the right (west).If your in an area where off air antenna works get locals from antenna and 72.7 for everything else.I know these 2 sat are eastern arc but I have used them west of texas.
