Okay, when I say 180° what I'm meaning is directly south, or true-south if you will (0° being true north).

Sadly, it would appear my Viewsat Ultra doesn't have any provisions USALS or DISEQ1.2. All you can do is manually move it east/west and memorize the location. This is annoying, but perhaps not that big of an issue once its aimed properly.

You've confirmed I was on the right track with my approach so I'll try again when I get a chance. I think what may be happening is my receiver on the installation screen is only looking at one polarity on the LNB. I'll have to force it Vert and Hor and try each.
