I think ham radio tower installations have far too unpredictable
potential failure modes to make generalizations. Many are short enough
to be relatively stiff and would tend to lay down in the case of a
failed guy. Some are overloaded and/or vulnerable to twisting, which
would tend to bring them down in a heap. Others are poorly maintained
and could fail in all sorts of ways. The results could be different in
every case, and I've seen pictures of several of them. If I was making
rules for private tower installations I'd require that set back as well.

The point wasn't about saying that tall commercial towers are built like
most ham towers or that they should be. There was a statement made that the
"lay down" failure of this tower is a reason why municipalities require the
tower be set back on property lines more than the height of the tower
(referring to ham towers). My point was that most ham towers wouldn't fail
that way.
