I had a metal fabricating friend build, on site, a five foot elevator to
hold the rotator, thrust bearing and beam, sliding on simple, parallel, barn
door sliders on a free standing 50 foot tower.
Works great, I can work on the antenna, etc., at ground level, no climbing
and it has served me well for more than 10 years now.
If a storm is pending, I just lower the elevator and hoist it back up again
afterwards.
