Also, as Bob Bruninga will tell you, set the EL at 15-20 degrees.
Following Bob's advice here for fixed elevation of 20 degrees works well. I've got my 6 element 145 MHz and 8 element 435 MHz cheap yagis on a TV rotor.
On 145 MHz I can copy and decode the AO-73 weekend mode beacon ~37 mW at 700 miles range with no preamp.
I've found that the tighter beamwidth of 8 elements on 435 MHz requires closer tracking (manually) and occasionally I need to wait for the satellite's elevation to get low enough to get back in the antenna pattern.
A basic setup like this will get you on the air. There is plenty of room for improvement but that is part of the fun too.
