360 + 90 = 450. Not 420. Use all of it if you can, but SatPC32 will seldom go the whole extra 90 degrees. As noted by others, the ability to do the back flip, 180 degrees of elevation, is usually of more utility.
North or south stop is religion, not science (though I'm sure someone has done the math to prove me wrong on that). Your preference. I use a north stop, even though I'm located fairly far north. -- Mark D.

I have no operating experience with satellites.
I am installing this G-5500 az-el rotator on a satellite ground station and I am using SatPC32 tracking software and an ERC interface. Everything is operational, so far...
I am trying to decide whether to use 0 to 360 degrees or 0 to 420 degrees on the azimuth rotator. The station is located in Eastern TN, USA. The 0 to 420 uses all available rotation but then the meter readings are not as useful. Are there any preferences on this?
From a practical, operating point of view, should the azimuth mid point or home position have the antenna pointed North or South? Or some other direction?
Thanks for your input.
