Please replace the above with:

There is no useful phase information contained in the
standing wave current phase measurement. Therefore,
the standing wave current phase measurement alone
cannot be used to determine the percentage of a
wavelength that is occupied by the coil. The
standing wave current amplitude measurement does
contain some implied information about the underlying
forward and reflected waves, e.g. they are equal and
out of phase at a point where the standing wave amplitude
is zero.

How's that, John?
