Well, no you haven't. Why do you keep saying that?

Because it's true. Here are the equations again.

A loading coil exists in a standing-wave antenna.
The forward current through the loading coil is I+.
The reflected current through the loading coil is I-.
The net current at any point in the coil is I+ + I- (phasor addition)
The magnitude of the net current depends upon the phase of I+ and I-.

Itot = I+ + I-

There's the equation that I have already posted many, many times.
Sorry you missed it.

A rough estimate of the net current at the top of a loading coil
can be had by estimating the number of degrees occupied by the
coil and assuming a net current cosine function through the coil.
