     I believe the article to which Jim refers can be found in NCJ Jan/Feb 1992, which itself is a reprint of two articles by Stan W7NI from the Sept/Oct 1982 and March/April 1983 (ancient history!) NCJs.  The article is titled Antenna Mast Design.  

     Dick K5IU also wrote a series of articles on the calculation of Yagi wind loads.  They are:  Determination of Yagi Wind Loads Using the Cross-Flow Principle; Aerodynamic Balancing: Part 1 and Part 2, found in Comms Quarterly Spring 1993, Summer 1994 and Winter 1995, respectively.  

     I know I bought reprints of K5IU's articles through ARRL.  I believe K7LXC sells/sold the Antenna Mast Design reprint.  He'll jump in here, I'm sure.
