[QUOTE="moonbase, post: 1052118, member: 178786"] Try 40.5 West, it has strong signals and is circular polarity so much less emphasis on LNB skew. Also, remember that the LNB throat aperture needs to be positioned closer to the dish than the focal length. The LNB should be positioned so that the focal length of the dish is approximately 9mm to 11mm inside the LNB depending on the beamwidth angle of the dish. I think the f/d of a Precision 1.8m dish is around 0.36 so check that the flat scalar is correctly located on the LNB, there should be some f/d alignment marks to position the flat scalar. It might also be worth trying to detect a signal using a satellite receiver and a small TV to see if it picks up anything? [/QUOTE]
