Further, I meant to point out that 100% skin depth only occurs to
~17Khz. And, while #18 may be ok for a max of 16 amps when used in
chassis wiring, it is only rated at ~2.3 amps for power transmission ...

Anyone know how many amps commonly flow through a current node on a 1/4
or 1/2 wave ant? Now, that's the real question, isn't it? And, if all
that power is all concentrated in just the skin of the copper, wouldn't
there be a degradation of power handling directly related to frequency?
