Hi Dick.
Dick Weber, K5IU, has written a series of articles on this subject. The
articles (that I know of) are;
-Determination of Yagi Wind Loads Using the "Cross-Flow Principle",
Communications Quarterly (Spring 1993)
The above article is math intensive. Dick condensed this information
into;
-Yagi Wind Loads, The DX Magazine (May/June 1995)
Dick expanded on the subject in the following two articles;
-Aerodynamic Balancing: Part 1, Communications Quarterly (Summer 1994)
-Aerodynamic Balancing: Part 2, Communications Quarterly (Winter 1995)
These two were condensed into:
-Yagi Wind Loading, The Dx Magazine (July/August 1995)
They are all good reading.
Hope this helps.
Bob, W9UI.
