At low frequency, I understand how this is a good approach (though this
discussion was about the W2DU style choke balun). But at higher
frequencies, I am concerned that the turn to turn capacitance might
provide a low impedance path that parallels the choke. A string of beads
does not have this problem.
Hi John
"For what its worth", I have wounf the coax around a single ferrite toroid
with the exact amount of turns and spacing so the impedance along the
conductor of the coax outer shield was maximum, as in parallel resonance.
I cant claim that it does any better job than any other "1:1 balun", but it
worked for me.
My point is - The turn to turn "stray" capacitance doesnt necessarily have
to be a source of performance degradation.
