Ok as I try to see your thinking widening the arc could solve your problem and the travel I was speaking of was in the sky longitude wise. Could also be your arc is to wide and you need to narrow it up a bit. Start by finding the farthest east sat you can see (tv that is) and gently push up and pull down on the dish. Did signal change any in either direction? Note your results. Now find the farthest west sat you can see (tv) and repeat your up and down test. Did you receive opposite results? If so rotate the entire assembly on the mast towards the direction that produced a stronger signal when pushing up.

Not much maybe a degree or two. Repeat above as many times as neccasy until you get a drop in signal on both ends of your arc when you go up with the dish and down. You are now centered on your viewable arc.

Go back to center. Is your south sat showing signal? Work your way around your arc and note readings at each sat. Use USALS to move the dish. Plot your arc on a piece of paper and look at how the readings are which should indicate to you the shape of your arc. Basically lower declination (dish elevation) widens the arc and higher narrows the arc. Motor elevation places the arc in the sky. So if you are getting pretty even results all the way across your arc but low you need to either raise or lower motor elevation. If you are reading the center of your arc and not the ends you need to lower declination and raise elevation.

Hope that helps a bit
