I find this to be an interesting conflict. If you look in the Rohn book, you
will see that ALL fifty foot 25G towers have TWO sets of guys even at the lowest
wind speed of 70 mph. Glen Martin says one set is usually enough. So now we
have two manufacturers with conflicting advice . . . how do we apply the LXC
Prime Directive to this situation?
As for taking ALL three of the guys off of 50 feet of 25G to lower a Hazer, that
would make me VERY nervous since Rohn says the maximum height for an unguyed
Rohn 25G is 40 feet and that is with only 1.5 square feet of antenna on it and
then only in the lightest wind areas. I realize you won't be intentionally
lowering your Hazer in the wind, but it still makes ME nervous since I am not
that good at predicting unscheduled wind gusts . . .
