I have a Cushcraft 40-2CD on a TIC RingRotor, and a TH6DXX on a homebrew
"swinging gate" sidearm. Here are my thoughts:
* The RingRrotor does not suffer the start up problems (wherein
you sometimes must go one way to start, and then reverse to get to where
you want to go).
* The RingRotor does occasionally ice up.
* Early models of the RingRotor had RFI problems (now solved).
* To truss a boom from a RingRotor requires an extra set of parts,
which costs more money.
* RingRotors are expensive now.
* RingRotors can be hard to climb around.
* RingRotors are generally easy to work on.
* RingRotors take 90 seconds to go 360 degrees. A T2X moves at 1
rpm (a whole lot faster when you are in a contest).
* The Swinging Gate requires re-aiming at least once a year, which
is never required of the RingRotor.
* The Swinging Gate has 310 degree rotation. The RingRotor is 360
* The Swinging Gate uses a Ham-M, Ham IV, or T2X -- and those have
well documented maintenance issues: start up (mentioned above) and
needle wobbling, as well as the need to replace starter capacitors.
* There are two kinds of people: Those who have never had
ballbearings fall all over the shop floor, and those who have worked on a
CDE/HyGain rotator motor.
