Ted, W3TB gave a presentation at the March WCARES Monthly Meeting on Windom antennas. Ted discussed the use of Azimuthal Equidistant maps for antenna planning and aiming, gave a demonstration of modelling the Windom using the EZNEC demo and discussed building the Windom.

Ted’s presentation files are attached:

1 – the Azmuthal-Equidistant map of the world centered on Franklin
2 – the PowerPoint that Ted used in the presentation
3 – the article from 73 Magazine, Sept 1980, about the Windom (The Internet Archive maintains copies of this magazine: https://archive.org/details/73-magazine )

Additionally, an image combining the Franklin azimuthal map and the antenna plots as shown above is here.

And try out a simple website demo to see how rotating the original antenna plot compares with locations on the map:
