Default Current across the antenna loading coil - from scratch

The current you measure with a clamp on meter or any other reliable
current meter that does not greatly perturb the circuit is the current
that causes radiation, it is the current that causes heating, and it is
the current we would use to calculate power.

There's absolutely no argument about that. Both forward waves and

forward waves and reflected waves cause I^2*R losses. Stating such
obvious technical facts is a diversion and a waste of words.


Cecil,

Please humor all of us.

You now seem to agree the current we measure, which is the current that
causes radiation, causes heating, and that we can use to determine
phase or power levels is what Roy, I, and a dozen others have been
saying.

So what exactly is the importance of this current YOU are talking
about? Since it does not cause radiation, does not cause heat, and does
not determine phase....exactly what does it do?
