Well said.  A friend of mine put up a 40 foot 45G without guys and a
tribander on top with rotor.  I did not climb it but watched while two other
friends did.  It was kinda scary just watching, but the tower was steady as
the work was done.  If it had been 25G I likely would not have had the
courage to even watch.

Yes, I can tell you...No, absolutely not! 25G isn't self-supporting at any
height. Additionally, if you were to erect this 40' tower without guying it,
someone would have to climb it and install the antenna...making for a very
dangerous situation. The ice loading situation that someone else mentioned
is another reason not to do this.
Granted, hams have used this technique and gotten away with it for
years...but that doesn't justify doing it. You should either guy the 25G
installation or use self-supporting tower.
