Well, it probably is... but how many per leg? And what are they attached to

And how big is the base of the tower. A tower that is 3 feet across has
1/3 the load of a tower that is 1 foot across.
A 400 foot tower that's 10 feet across with 40 bolts isn't putting a
huge load on any one bolt.
The are claims in a discussion on Face Book that an anchor bolt, "5/8 in. x
12 in. Hot-Galvanized", is suitable for a free standing tower. Someone even
claims it is used for a 400' freestanding tower. It doesn't make sense to me
but I might be overly pessimistic.
I hate to start lengthy discussions and this might be one of them so,
please, comment only if you have a well grounded answer. I'm sure there are
plenty of opinions about it like my own, but I would like to know if my guts
feeling is right or wrong. What I am afraid of is that you can pull out an
anchor bolt like that right out of curred concrete.
