1164678	2010-12-25 07:36:00	I have to set up a satellite dish in Auckland to Optus D!. The Elevation angle is stated to be 44.4 degrees. My own dish, which was set up by an expert, seems to be set at 18 degrees. Can anyone explain where this 44.4 degrees is measured to and from? Any help gratefully received.	arjay (1202)

1164681	2010-12-25 08:29:00	where are you measuring the degrees from? if its off the writing on the dish, it only meaning full IF the pole is perfectly straight.	tweak'e (69)

I think this is the answer. the angle that the LNB is offset from the centre of the disc is subtracted from the 'offset angle' given, (44.4degrees in Auckland) so the dish is leant back at about 22 degrees. Thanks for that, Arjay	arjay (1202)
