On page 6-29 it says: " "Experience has indicated that a secrion of wire
approximately one half wavelength long, wound on an insulating form with
linear pitch (equal spacing between turns) will come close to yielding a
resonant quarter wavelength. Therefore, an antenna for use on 160 meters
would require approximately 230 feet of wire, spirally wound on the
support.

Art may have discovered the above alone but he was very unlikely to have
been the first discoverer.

yeah, but art's 160m antenna fits in a shoebox.
