I also eventually agreed that I went too far to suggest one *could* tell the

but it might take some time. It was a 'by the way' sort of thing; it seemed
to be almost corroborative but it was definitely was incorrect although not
very important in the overall discussion. Thank you for having corrected me
before. I thought I previously had submitted to the lashes of the whoop
haung (or whatever they call that thing at ARRL that you use to punish
hams).

Thanks, I had missed that posting. Did you also conclude, then, that all
the boxes contain the same number of "electrical degrees"?

Yes, all the boxes contain the same number of electrical
degrees. That's why we can calculate the number of
electrical degrees at the impedance discontinuity.

Hint: That number of electrical degrees for a capacitor
is the same as the gamma angle for the reflection
coefficient.
