Y = 2272 : 2 = 1136² = 1290496 : 346 = 3729.7 : 4 = 932mm is correct.. The dish is basically an optical lense. If the focal point is out by 22mm they would be significant lose... The Focal distance 932mm should be measured from the center of the dish to within 10 to 15mm inside the LNB throat...For the final adjustment use a satellite meter for best BER MER, and optimized polarization, the V and H orientation.
