To help clarify the elevation discussion, I have added a drawing of a LEO orbit passes relative to a station's antenna to the web page:

http://www.ew.usna.edu/~bruninga/rotator1.html

It clearly shows how most satellite times are below 30 deg, and 10 dB more gain is needed to work satellites at those near horizon angles compared to above 50 degrees where satellites are 10 dB closer and spend less than 5% of their time.\

I think the visualization helps a lot in these discussions and shows how only a simple TV rotator and small beam is needed for all LEO's..

By the way, I am not pushing the rotator interface indicated in the web page above. That web page is over 6 years old, and I only keep it on-line to encourage all other Satellite Tracking programs to add the same simple 2-bit TV rotator interface that would make LEO satellite operation so simple and innexpensive, that it would help newcommers join the satellite operations at minimal cost. There just is no need for a "typical OSCAR array" for LEO operation. We do ourselves a disservice by only having tracking programs that can only control $1000 rotators when a simple $70 one will do perfectly for LEO's.
