If you need to control the servo with an old analog receiver it probably would be easier if it also controlled the actuator motor. Wouldn't be very user friendly to use 3 components to watch satellite TV..... the Gbox for actuator, analog receiver for polarity servo and the AZbox for channel tuning.

The analog receiver I have, does not support KU band, cband only. I thought through the FTA STB I could control both and thru the analog receiver I could switch the Horz and Vert.
