You could have a cable rubbing a groove through a brace.
It catches on the groove when near the top.  I had this problem
and had to bend the brace back.

The other thing is that if your antenna isn't perfectly balanced,
the tower leans more as the overlap decreases.  I have this problem
with my MonstIR on my HDX5106.  Works fine w/o the antenna but
with the antenna installed, it starts vibrating the last few feet.  I 
just don't crank it up the last few feet.  There is no fix for it AFAIK 
except getting a more balanced antenna.
