I am relaxed. Why, you may ask? Because my tower/antennas are
conservatively engineered (aka following specs and manufacturers
recommendations) to avoid problems. What kind of problems? Failure
from overloading, and failure from ingnorance about the system.
We recently had a report from a guy with the bent water
pipe mast, after 20 years of service. In the long run it's cheaper
and less angst-evoking to KNOW something like that will NEVER happen
here.
You weren't involved in building the Tacoma Narrows Bridge,
(great video, if you've never seen it), were you :.)
