Might depend on the tower and the wind, and, certainly some psychology.
I've been up a several hundred foot tower, and it certainly moved. Not
abrubtly, more like a sort of swaying with a period of several seconds.
Not unlike standing on a dock, but smaller displacement. Hard to
estimate the displacement though, because there's nothing to reference
it to.
For that matter, if the wind is blowing, even a solid rock pinnacle
"feels" like it's moving. Maybe it's because once you get a few hundred
feet up, you don't have a visual "ground reference".
