Let's consider a 50 ohm ideal transmission line with a 25 ohm ideal

I suspect what Dan is referring to is the LCLCLCLC
equivalent circuit for a transmission line. A horizontal
wire over ground is a one-wire transmission line with
Z0 = ~SQRT(L/C). A radiating antenna can be considered
to be a lossy transmission line.

A #14 horizontal wire at 30 feet calculates out to be
Z0 = 600 ohms so L/C = ~360,000. I'm pretty sure that
is the L and C that Dan is talking about - the same
L and C in which the standing wave energy is stored.
