Most rotators use a similar scheme for motor control and indicator. Their
operation is sensitive to voltage drop so the proper sized cable is real
important. Hy-Gain recommends the following:
Max. length Gauge for Terminals 1 & 2 Term. 3-8
If you've got some smaller wire, you can twist multiple conductors
together to give you a 'bigger' wire size.
The well-known technique of mounting the Hy-Gain starting capacitor
close to the rotator is a good one. I think the Japanese rotators use DC
motors and I'm not sure about the Orion.
