Default 4:1 Current Balun Common Mode Impedance?

Did you also measure the phase angle for those readings?


Yes, at resonance it was, of course, 0º. From 3 to 30 MHz. it varied
between -61º to -81º.


Is the inductive side of resonance of no use in
that type of balun?

Its resonate at about 1.58 MHz. Whatcha going to use it for? Broadcast
AM radio?

I wasn't talking about that particular balun just that
particular method of construction. If a balun like that
one were made resonant at, say 7 MHz, would it still be
useful at 4 MHz? at 2 MHz? In other words, what is the
shape of the choking curve below resonance for that
particular method of construction?
