I wouldn't worry about putting something up on a chromalloy mast, as
long as you use a platform down 8 or 11 feet from the top for the
rotator, and let the thrust bearing and the rotator handle the side load
on the mast.
I will have a C31XR up 9 feet from the top on a mast. Also take a look
at http://www.qth.com/ka9fox/tower/ , KA9FOX's installation which seems
to have more up there than I will have. He's had all that up for maybe
three years now?
