This test works only with a current balun. If done with a voltage balun,
the impedance should be very low.

Although there are ways to test for the proper functioning of a voltage
balun, that is, to test for the voltages at the output terminals being
equal and opposite with respect to the "cold" side of the input, they
don't tell you how effective it'll be in stopping common mode currents
on feedlines. In fact, certain imperfections might improve the
performance of a voltage balun in that application. I don't recommend
using a voltage balun for feeding antennas for the reasons I gave in

I apologize for the error. Thanks very much to Owen Duffy for pointing
it out to me.

Thanks for the replies, Roy. They were pretty much what I suspected,
but hearing it from you is a nice confirmation. Why don't you make a
small white paper on your site covering this subject?

As usual, I didn't get my original post, and none of the replies, except
for this one. It's nice to have google to pick up what my newsfeed misses.
