You know you can't move satellites in orbit to match the plate, right? LOL
How close/how far apart it "can see" the various satellites you can only determine with YOUR particular dish, and how you set it up. It depends on size of dish, focal point, location on Earth, etc.
I was thinking about putting it on the 10-footer. I'm just curious if 2 degrees is too close together and with the maximum stretch I could get out of it is. So can I do something like 97-99 101-103? 107 is about true south of me
