Again it is the LC ratio that must be kept for resonance."

I don`t know enough about Art`s antenna to deny it. I do know that
resonance depends on the reciprocal of the sq. rt. of the product of LC,
not its quotient.

Explosive results from an inductor were introduced by Kettering, I
believe, through interruption of battery current through an inductor to
generate a very high voltage spark to ignite the fuel air mixture within
the cylinder of an internal combustion engine for automobiles. Just as I
doubt the inclusion of a pendulum in Art`s antenna, I also doubt the
presence of an interruptor to discharge either the capacitance or
inductance in the resonant antenna.

If Art`s antenna is novel, useful, and not completely obvious from prior
knowlege, he may profit from it. I wish him all the best.
