i am located in west texas and am having trouble getting a good signal that does not drop out with lite rain .my hd locals come in on 61.5 and everything else on 110/119/129. i have a tree line to the south, but a clear shot to the east. could i switch to a 1000.4 dish and get everything that way . a house down the street has a dish pointing away from a tree blocking the entire sw side of the house which gave me this idea.
