[Amps] unun

[R.Measures]

**   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.
