Its properly called circulating currents. Imagine two wires same length same signal. If they touch at the same place on both wires, same phase and amplitude, no issue. Now a different experiment... one of the wires is straight, the other is folded so that you can touch them at different points. Now, touching at different phase and amplitudes. What happens? You know the answer.

I am not sure what effect crossing the wires has. Has anyone done any real testing of this or is it just theory or a wives tale? Did he stumble upon the holy grail of radials? Most of the results of the radial field are from the first 50 percent or so. You do not necessarily have to have 66 ft radials on 80m to work and get out. Put out as many as you can as long as you can and shorter radials are fine too.
