Are they rated for 110 MPH? They have some pretty good size antenna arrays at the top. Assuming 30sf at 200ft and 110 MPH I come up with at least 285,000 ft-lbs! And I thought I had problems! 73-- Dave Armbrust - AE4MR ARRL WCF Section Manager (941)378-1701 Fax: (941)929-0040 -- FAQ on WWW: http://www.contesting.com/FAQ/towertalk Submissions: towertalk@contesting.com Administrative requests: towertalk-REQUEST@contesting.com Problems: owner-towertalk@contesting.com |
