Greetings.. I've acquired a 20x36 directtv worlddirect elliptical dish last week. It seems to require more precise alignment than my larger BJU dish, but it performs just as well, from what I can tell (I tested it with the 30W sat, and the 97W.) The dish mount allows it to be skewed around its axis like you would normally skew an LNB. My question is, should the dish be skewed, or left horizontal? I have already replaced the LNBF it came with, with a standard linear one, and the reception is great with the LNBF skewed and the dish not skewed, but I wonder if the quality would improve even more if I skew the dish, too? I ran out of time and didn't experiement with that. What's the theory on that? It's on a fixed mount.. Thanks.
