K0XG rings meet the bill, seven on my Rohn 65. Some startup fixes and
then no problems 5 years. see my QRZ page. A huge complex project though.
Would I do it again - no. I'd go with swing arms with 20ft masts, top
and bottom supports, 2 yagis per. It's rare I need fully independent
beams and almost never 360 degrees for me. I did the CAD work for these
swing arms. Some CNC plasma cutting of 1/4" steel plate and welding
needed for a fraction of the cost. Uses a standard mount rotator, eg
Orion 2800, etc for rotation.

The RT-4500HD looks very interesting, especially with the Green Heron
control box and the K7NV style mast clamp. It would be nice to see a
quality ring rotator too, someday.

Hi Rich:
The RT-4500HD DXE Rotor will be available later this year. We have been
doing aggressive testing here and we have made significant improvements.
We will have a few beta units in the field very soon. We'll let everyone
know when they are ready.
