Anyone heard of this??-- installed a new 3-LNB dish to upgrade to HD. Sats 101 and 119 have good sigs, but 110 is in the 30's. If I rotate the dish (tilt) to the stops (140 degrees), the 110 transponders get up in the 50's-- like if I went 90 degrees, sigs would be where they should. Any chance the problem is polarization, LNB is installed 90 degrees out?
