Please, I'd like some more discussion of this question. I've seen
before that baluns on ladder line can be lossy, but I'm not about to
get a balanced tuner, so it doesn't really help. What happens if you
connect the balanced line directly to the KAT100? Or, in my case, to
the KAT2? I haven't had any problems so far -- maybe low power makes
a big difference, or maybe I've just had antennas which were
reasonable in some way. I gather it's possible to get unpleasant
currents on the case, mic, or paddle. Is that exactly the condition
in which the balun will be lossy? Does connecting the ground screw
on the KAT2 (or the one on the balun?) alleviate the common mode
current problems?
