Hi Ron, maybe it is my misunderstanding!
My logic goes like this:
Take the example of an electrical quarter wave of 75 ohm line. One end is terminated with 100 ohms, and the other end with 50 ohms.
If you were to cut this line at some random point, and measure the impedance (at the design frequency) looking towards the 100 ohm termination, it would be somewhere between 50 and 100 ohms, depending on where you cut it.
Measuring towards the 50 ohm termination would give the same reading, I think?
If this is correct, then at no point on the line is there a step change in impedance, so there should be no reflections…
I’m very open to correction :o)
