I can't seem to get anything with my new dish . I have 2 different receivers and suspect the LNB is bad. What strikes me as strange is the fact that the LNB is labeled for the low band only (Low 9.75 GHz ) with no mention of the high band on the label. I I have the Invacom SNH-031 with a Winegard dish. The two receivers I tried are a Twinhan Starbox and a Fortec 5900. The twinhan shows no signal while the Fortec shows a constant 70% signal with 0% quality, no matter where it's aimed. Should the LNB show both the low and high freq's on the label? I have a directv setup so I know there's no interference or obstructions. Help !
