Skew adjustment comes from were they are in space.
So for instance any Sat over 28°e on the ground at 28°e will have 0 skew. As that is their horizon generally speaking. So for instance if your are setting up a motorized dish in the UK because you are for the most part at 0° because you are on the Merredin
your reference sat will be at 0.8°w and will have 0 skew. Because that sat is closest to your longitude.
The further the sat is east or west of you the more the skew you will have. If the sat is more east of you it will have a clockwise skew as you look at the dish from the from the front.
The skew will be anticlockwise if the sat is west of you.
All skew is turning the lnb so it matches the horizon of the sat you are looking at so the horizontal and vertical signals match up and you get the strongest signal. So any sat co located will have the same skew.
