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.
thats exactly what i mean .spot on
@pedro2000uk
do you mean the final position of the 3 feedhorns on the arc line when facing the LNB from the front?
