The reflection may be incomplete unless either a hard short or complete
open-circuit appears at the source where the generator meets the
transmission line. If the source appears as a complete short or open the
reflection is total.

Hmmm. I wonder if the phase change on re-reflection the same as it does
on reflection. If it does, and the transmission line is a half wave
long, the Bird wattmeter readings would be real hard to explain.

And isn't it true that if there were actually a real hard short or a
complete open circuit at the source, there wouldn't even be a signal on
the transmission line?
