This is, of course, referenced to the feedpoint signal
at zero degrees. The phase of a traveling wave changes
45 degrees in 45 degrees of wire. The phase of the
standing wave changes no more than a couple of degrees
in 45 degrees of wire. Sorry for any confusion that
might have occurred because I neglected to explain my
reference phasor.
