I doubt the recommended lengths in that article are very useful.
Factor in an uncertainty of up to 5% to allow for variations in wire
velocity factor, further uncertainties due to the environment (ground
conditions etc), and plain errors because he has assumed that a wire
resonant at F will also be resonant at 2*F, 3*F, 4*F etc, and the
recommended "good lengths" become pretty meaningless.
