Hi Bruce,
I use two 6' roof towers from IIX Engineering -- don't know if he still
makes them, but they also have a rotator plate. One holds my 5 el 10M yagi
and my 2 el 20M Moxon -- uses a G-800S rotator. The other holds my 7 el 6M
yagi, my 11 el 2M FM yagi, and my 12 el 2M SSB yagi, with an old Alliance
rotator. Neither uses a thrust bearing, both have been fine for 5+ years.
Check out my web site for pictures.
73,
