     Differences in humidity of different parts of the air? Differences in
ground conductivity/resistivity? Non availablity of a good 'arcing' parth?
Height above ground?

    Inductance may not be the issue. The copper strap has much more SURFACE
AREA and has much more contact area with earth than a copper wire. In ground
system construction in poorly conductive (rocky) 'soil', using 3 inch or more
copper strap greatly improves the performance of the ground system.
