HI All
In regards to the balun, how does it work when the impedance of
the line keeps changing? If you use a 4/1 balun, some
frequencies will be 300 ohm impedance and it will work, but at
some frequencies, the impedance will be as high as 2000 ohms, and
it seems that would be kind of hard on the balun if you're
running any power. 73
