The skew isn't a function of the dish, it's just a function of the orientation of the lnbf vs vertical or horizontal. Hopefully the lnbf came with instructions that show what orientation relates to vertical or horizontal, when facing south, then, using the web page Steve referred to orient the lnbf to give the proper angle. If you want to be exact, you can use an inclinometer, even a home made one with a protractor/string, but I've never found it to be that critical, unless there is a similar SR signal on the other polarity that is interferring. I usually just set it by eye approximately, and it is good enough. The only time I have had trouble with skew has been with a few DCII signals. Since they have a few common SR values, like 19510, you might happen to find the exact SR on the opposite polarity, so skew becomes more important.
