Ed, While in lived in the D.C. area some years ago, I had a 160ft stick of
Rohn 45 with a similar mast as you described. Eight feet of my 24ft mast
were in the top section which employed 2 thrust bearings and a T2x rotator.
Above was a 4 element monobander for 17, a Hygain 204BA, and a HyGain
Discoverer 3 (3 ele 40mtr monobander). That worked well for me for the 9
years I lived there. -Mike

It was always what I learned. And seems to make sense from a moment arm
standpoint.
I would be interested in what others do in their designs.
