? The Rohn 55g Bearing plate sure is expensive. I see two other
possibilities.

mast/bearing.

I have no idea what the thickness of the Rohn bearing plate is as
compared to a beacon or rotor plate. I'm hoping to put up a full size 4
element 40m beam some day, so the system will need to handle a good
300+lbs.
Hiya, Rich --
The beacon plate is FB if you don't mind drilling it.
As for an intermediate bearing, I'd discourage it. The plates are not
precision items and you'll just introduce bind into the system. Since all
you're trying to do is capture the mast, put the rotator plate in the middle
and skip the bearing - cheaper too. And the upper TB carries all the
weight anyway so a middle bearing doesn't provide any structural help.
