At one time I had the 4L 40m KLM at 132 feet on a Delhi guyed tower.
At another time I had a wind come through here that broke the boom of the
KLM but did no damage to the Delhi tower. That's a 42 foot boom with lots or
torque.

So now we have two tower manufacturers, Delhi and Rohn, that state or imply that
a sensibly guyed three legged self-supporting tower is fine.
None have said not to guy.
