>>73, David K4ZZR
The building code in my area (eastern MA) requires 90-mph-wind
survival, so I sent email to US Towers (at the address given on their
website) asking whether any of their towers can survive 90-mph wind,
and if so, with how many sq. ft. of antenna on top, and with what
guying. I got an unresponsive reply so I asked again. This time I
got no response at all. I conclude that no US Towers tower can
survive 90 mph, even with no antenna.
On the Rohn website, you find very detailed wind-loading info.
