I think you are missing something here. If the dish is pointing at 34.5W and you are receiving KU, everything is centred. Looking at Pipino's pictures I'd guess the C band LNB's are about 15 cm off centre which with the 1.2 metre LNB arm equates to about 7 degrees. The dish must be moved 7 degrees so the C band LNB comes into focus. Obviously the tolerance that Pipino is talking about is the small aberration due to the LNB being slightly off centre, not some tolerance caused because the dish is not correctly orientated towards the satellite for an off centre LNB.
