    Like all other towers, there is a top plate with a thrust bearing and a 
rotator shelf somewhat below the top. The mast is attached to the rotator and 
goes up through a 6-8 inch pipe that functions as a mast 'retainer'. The 
antennas attach to the mast.

    There is a rotator shelf plate down a couple of feet below the top of the 
tower.
