I am using a Chaparral lnb that Sky is using. I get a few channels in HD in the rest i can't see. There is a channel that comes and goes during the day (NETGEO) and some other SD channels too. So i am not sure if the Sat is movig during the day. I am using a 2.5 mt antenna here is Dallas. I was using a universal lnb with the standard receiver and switch to the chapparal lnb to be able to use the HD receiver. Do i need a stronger LNB or is there such LNB to be able to pick up the other HD channels?
