Hi Harvey, all,
                The reason you cannot use wirelength considerations 
in describing the action of what *really is* a 1/4 wave resonator is 
that the wirelength thing applies *only* when there is little or no 
mutual inductance between sections of the wire. The velocity of 
propagation then approaches the free space 1/4 wavelength. If you 
coil the wire up, the mutual inductance suddenly comes into play and 
now the propagation velocity is inhibited. In effect that means that 
the waves travel up and down the resonator length/height in the same 
time it would take them to travel ???,000km in free space. For that 
reason, Tesla's resonator is described in some quarters as a velocity-
inhibited resonator. In fact, the mutual inductance gives the 
structure a Q way beyond what a straight length of wire would have.
