It's all explained on my web page, Jim, where the forward current
is assumed to be a constant magnitude through the coil and so is
the reflected current. It is the net current that is changing
magnitude because of the superposition of the forward current
and reflected current. Net current is much easier to measure
than are the component currents. We can deduce what the component
currents look like from the net standing wave current.
