Fred:

As my last post gave away, my chokes are constructed on math and
observation in practical work... (well, prayer too grin)

I see roy is recommending 10x the impedance of the feedline (coax?) for
the choke/balun, minimum (I am guessing here a bit), he obviously knows
what he is speaking about, however, at 160m when you are struck with the
physical dimensions of the choke/balun needed--well, at those times I have
accepted a 5:1 ratio of choke/balun impedance to feedline impedance...

.... but then, I am here to learn ...

How can I test how well a choke balun is performing? I know how to test a
transformer balun, but am cluless as how I can compare several different
choke balun approaches.
