	I assume that the expression "resonate as an electrical 1/4 wave"
refers to the behavior of a resonant 1/4 wave vertical radiator over
conducting ground.  Note that in this case the effective antenna length
is really 1/2 wave, as there is an image antenna "below ground".  If
this just means resonant in the lowest mode the system will support,
that's another definition and should probably use another name.
