I have the H20 receiver and can only get a 74, 75 signal on sat C. I can get a 94-95 on my samsung HD receiver in a different room. Is this a receiver, line, or dish problem? Is this possably a splitter problem? The tech put in the new 4x8 when the 5 LNB dish was installed. I have had 3 techs come visit to fix my signal problem, no luck. My old 3 lnb dish never lost its signal, I was watching local news DURING Hurricane Charley (under generator supply). Now a simple rain storm causes signal loss.
