[TowerTalk] Is spacer necessary between HAM II and tower rotor plate?? Reply de K0FF

David, whatever else you decide upon (mechanically) as suggested by other
contributors, let me make a recommendation concerning the wiring part of the
rotor installation. I highly recommend installing AMP 9 pin connectors on
the rotor cable and on the rotor (via a flying lead, or "pigtail"). Also at
the control box end. This way if service or troubleshooting is needed,
individual wires don't have to be removed/replaced. It also makes it easy to
remove the wiring from the control box for lightning protection.

I set the standard years ago with these connectors, and fortunately, the
commercial world settled on the same arrangement. I've had them in 24/7
outdoor service for over 25 years already. Put the female pin into a male
body on the side that supplies the  power (like a receptacle ).

AMP connector on rotor: #206705-2 (female pins/male body)
AMP connector on Control box side # 206798-1. (male pins in female body)

Make sure you get the complete connector, for inline wring (both also come
in chassis mount versions). It has a body, pins , backshell, and cable
clamp/ Only a few bucks for a set. Use one set on the tower and one set in
the shack.

Available at Van Sickle or RS Electronics (NOT Radio Shack, RS is a
commercial electronic supply house).

PS I always go with a large rectangular hole in the rotor plate, mainly
because you need it for the bolt and steel rope cable to pass through when
using a mast winch. You're going to drill and tap the mast(1/2" thread) for
an attachment point for a mast winch aren't you?  Geo
