I put my AB577 up today at 45' with a 5 element 15meter beam on top.
Ive noticed it vibrating in the wind (it did this when I had it up
without the beam as well). Some of the top sections of mast shake
around - I figure this has something to do with the fact that the
sections of mast dont mate perfectly. Its hard to see, usually I just
hear it.
Should I worry about this? Does your AB577 do this in 30mph winds?

In a word, NO.
I suspect you may have insufficient upper guy tension...or possibly
that the clip-rings which hold some of your sections together are
stretched out, and not clamping tightly. If the latter is true,
try Ben at Ontario Surplus for replacements.
