Hello. First post, so please go easy This question *is* tower related, but somewhat less strictly radio related, so I'll try to be brief. I am thinking about building a tilt-up tower to get a small photovoltaic panel clear of tree shadow on some off-grid property I own. I've reviewed at least three plan descriptions (including one for the "tilt-up then crank-up 50' tower" plan by Ben Stone that no longer seems to be available) and each one specified design maximum wind load solely in terms of surface area (typically, in square feet). Maybe I'm missing some fundamental assumptions that don't require mentioning in the amateur radio community, but that seems woefully inadequate to me. At minimum, shouldn't there also be a maximum wind velocity/gust specification, e.g. "6 sq ft @ 40 MPH with 70 MPH gusts", or something similar? I'd also be interested in learning if the surface area specified is typically for the payload only or whether the surface area of the tower structure itself is expected to be factored in by the builder. Thanks for any insights you can provide.
