[TowerTalk] Which Thrust Bearing to Use

[john at kk9a.com]

I have much less mast inside the tower but I concur that there is no
reason to have three bearings on the mast (two thrust plus the rotator).

Jorge,

If this question is directed at me, no, I only use a bearing/bushing at the
top of the tower. I generally have at least 10 feet of mast (~3m) inside
the tower and I have always thought that the alignment issues with 2
bearings and a rotator was not worth any perceived benefit.
