Just exactly how many different kinds of alternating current do you
reckon there are, Cecil? :-)

The point is that the current in a pure standing wave has
a different equation from the current in a pure traveling
wave. Any fields and waves reference book will have those
equations. The current in a pure standing wave cannot be
used to measure any kind of phase shift between points
because the phase doesn't shift between points on a wire
or on a coil. The current in a standing-wave antenna, like
a loaded mobile antenna, is primarily standing wave current.
Why do you think they are called standing wave antennas?
