[TowerTalk] TowerTalk Digest, Vol 239, Issue 28

[Lou Laderman]

There are a number of structure wind zone maps that come up if you search for “wind zone tower”. It appears on all of the ones I saw, most of NY is in the 115mph zone. That said, the specific map and how it’s applied depends  on which version of the applicable code (EIA/TIA-222-[version]) how to calculate the stress on the structure is calculated. I believe 3-second gust is the most recent requirement, but the building code applicable to where your tower will be located is what has to be followed. 

Here’s a decent reference

Subject: [TowerTalk] New York state wind survival requirements for
   antennas
Message-ID: <d0d4a12805c658027cbabcb0577aad4558992fb4 at webmail>

I have a few questions regarding antenna wind survival requirements in
NY state and possibly the whole US. A local building inspector is
telling me that just like with towers, NY requires any antenna mounted
on a tower to be able to withstand a 3-second wind gust at 115 mph,
but I know that can't be right. If you have any knowledge or
experience in this area, please contact me directly at my email
address. I have not had any luck getting answers from the ARRL.

I'd also be interested to know if there is still an email reflector
for topics like this. I heard about one called "Ham-Law" but it
appears to have shut down a long time ago. 

Thank you,
Gerry KA2MGE
