I think most of the rotors you saw back then were CD. They were really
great for TV antennas OK for PDL-2.

I couldn't imagine anyone using a TV rotor on a moonraker. They used to use
the AR22 and TR44's (mostly 44's) on the smaller beams but the Ham M is not
a TV rotor, I used one to turn stacked 4 element Hornets, each had a 24 ft
boom.
The rotor was mounted at eyeball level down at bottom of tower and the
antenna's
were supported on thrust bearings. Had it up 5 or 6 years until 80+ mph wind
turned the hornets into pretzels. The tower and the rotor survived. RM~
