The older mechanical polarizers work exactly like a model airplane servo
motor. The 5-volt power is needed, but it will not move until you deliver
a repetitive pulse to it. The length of the pulse tells the servo which
angle to rotate to.

They usually expect a pulse about 1 - 2 millisecond in length to move
from one limit to the other.

Maybe you could just rotate the feedhorn manually until you figure out
a more convenient method.

Use standard and set the LO frequency to 10750.
You can replace the polarotor by its self.
