2. That it is not a true transmission line transformer, because your
transmission-line windings are not being fed with opposite polarities
across the *same* end?


Ian,
I wanted to give a more thorough reply to your question earlier, but at
the time a spontaneous reply did not seem to be sufficient. So, I have put
together an extensive tutorial on the subject of the theory, synthesis, and
practical considerations in the design of transmission line transformers
that is a result of over two decades of designing these things as a hands-on
hardware designer:

impossible, so now he has to prove that the solution cannot possibly work
the way that he knows that it cannot work. Whatever.


Please skip the personal rhetoric, and tell us how you respond to his
two main technical points about your transformer:

1. That it is simply a 2:1 transformer with an isolated primary and
secondary?

2. That it is not a true transmission line transformer, because your
transmission-line windings are not being fed with opposite polarities
across the *same* end?
