I am looking to set a pole in the ground and setup my C band dish. I have an actuator for it and a couple analog receivers and a fully mapped 4dtv receiver with all of the satellites. I need help in setting up the positioning of the dish with the receiver. I see there are positions available from like 3000-5000. Where would I set my true south at 72w with these numbers? How does the spacing of the numbers work? I would like to be able to have this work from 43w to 131w if possible. Is there a guide anywhere that talks about setting the dish positions and actuator setup?
