Probably the easiest thing to do would be to use two ring rotator
control boxes with a common set of external double pole
CW/CCW switches wired in parallel with the individual CW/CCW
switches in each control box (e.g. one switch activates both
control boxes simultaneously). This scheme would make it very
simple to touch-up the heading of one antenna if the two rotators
got out of synch.
