** Dennis -- Example: one 3-500Z in g-g config: The input Z varies
continuously from c. 30-ohms to virtually an open circuit during the 360º
of the input sinewave. Transformers are not happy campers with weirdo
waveshapes or out of phase E and I.. This is why a balun should not be
used with anything but something fairly close to 1 to 1 SWR.
