1. I used to get strong signal strength on all my 101 satellite transponders. Yestarday, after I upgraded to the HR20 and 5-LNB dish, I'm now getting weaker signal strength (average in the 70's) on the odd-numbered transponders on the 101 satellite than on the even-numbered transponders (average in the 90's). (Actual strength numbers from transponders 1-32: 83, 84, 80, 100, 79, 94, 79, 91, 76, 86, 77, 100, 74, 90, 76, 92, 75, 97, 76, 99, 71, 95, 79, 95, 79, 85, 75, 94, 75, 88, 75, 95.) I mentioned this to the installer, who said he had to set it up that way in order to make the HD picture look smooth around the edges or something like that. This guy seemed to know what he was doing, so I took it at face value. Does this make sense to anyone? I'm just concerned with losing half my channels with the next rainstorm. 2. The other thing he said was if a storm is approaching, "switch to transponder 4," which tends to get better signals in bad weather. He said the box automatically "resets to transponder 1" at shutdown and not to leave it on transponder 4 for a long time because it puts a strain on the LNB, leading to early failure. I tried to figure it out after he left, but I can't make heads or tails of it. Does this make sense to anyone?
