Hi, I have a Direct Tv slimline oval dish with integrated lnb's. The model on the lnb's is AU9. We get 97% level but only 1-8% quality. My husband is tryiong to get the 97.0 channels for the arabic channels. We have the coolsat 5000 reciever. Will this set up work and what are we doing wrong if it will OR can we change the lnb. We read somthing about circular and linear. This says integrated but we are lost. Please hlp!!! ASAP
