Free Standing towers typically fall down wind as straight as a string.
Which is one of the main reasons I like guyed towers and keeping them
50% of tower height plus the mast height away from the house. I do not
want my towers in my living room or bed room.
Unless, of course, it is Rohn 25. That stuff is so light and flimsy, I
have seen it fall on a chain link fence and not hurt the fence, but it
did demolish the tower.
