There's no email address on his qrz listing and nothing on his webpage here:
http://www.kw1o.com/Moxon/The%2020%20meter%20Vertical%20Moxon%20Project.htmI want to ask him about the dimensions of his Moxon, because his 20 meter band Moxon has a half-wavelength of 15 feet, 8 inches. That seems a little short if it is actually resonant at 14.07.....
I don't want to build according to his dimensions and then find that my antenna resonates at 15.5 MHz!
