Bill, Rick Craig - N6ND - had some poorly performing yagis partway up a big
tower which had steel guys proken up with insulators.  When modeled using
K6STI's Guy modeling program, it imitated the real experience.  Switching to
Phillystran made the poor performance end.  I think this was in the late
80s.
