For someone who claims to have a mechanical engineering degree, this is
Consider -- the wind pressure varies with the SQUARE of the wind
velocity. Antenna support structures designed for 90 mph winds would have
to be over 5 TIMES stronger to withstand 210 mph winds.
What you appear to be saying is that adding a single guy wire to an
antenna support structure increases it's capacity FIVE-FOLD!???
SHOW ME THE MATH!
