Actually, I don't believe the Brown et al experiments showed this conclusion
at all. Their extensive experiments showed an optimal radial length of about
3/8 wavelength (actually 0.41). This, with ON4UN's typical soil Vf of 0.5,
would yield an rf length of 3/4 wavelength. This 3/4 wavelength
Recalling Jim Brown's posting yesterday of Rudy Severn's excellent
recent work, the current maximum in a radial occurs at 0.25 wavelength
from it's open end loss will be minimized when that current maximum
is at the feedpoint.

From the antenna measurements, you can see that doubling the amount of
copper ( labor!) resulted in only 2 ohms
