Stan,
Older rotor plates had four round holes to accommodate a Ham 4 rotor. Newer
plates (maybe around 1970s? and later) have four oval holes that will
accommodate either Ham 4/T2X or the slightly different spacing of Yaesu rotors.
G-2800 fits fine inside Rohn 25. It is slightly smaller diameter than a Ham 4.

Subject: [TowerTalk] Yaesu Rotator Questions
Hoping someone with experience with Yaesu rotators can help me.
1. DX Engineering website and other websites say the G-1000DXA has one hundred
7/16” diameter ball bearings. The Yaesu G-1000DXA manual says ninety eight
3/8” diameter ball bearings. Which is the correct diameter?
2. I think the ball bearings in these rotators may be chrome as opposed to
stainless steel. I’m planning to put up a G-1000 DXA on Cayman Brac. Because
of corrosion should I buy whatever size they really are in 440 stainless steel
and replace them? Anything else I should do if I muster the courage to open it
up?
3. Am I going to have to drill the Rohn 25G rotator plate or are they already
drilled to work with the bolts to mount the Yaesu G-1000DXA?
4. Looked at the shock absorber plate after a post on here the other day.
Would four of something like this in between a couple of plates do the same
thing? Any need to have this or no? I’ve never owned a Yaesu rotator before.

4. In case I ever decide to buy one, curious to know whether a G-2800 will fit
in 25G top section with flat plate top?
Thanks... Stan, ZF9CW
