Didn't you once say "there is no such thing as a balanced antenna"?
Yep, but I was speaking more in terms of perfection -- i.e., that in the
real world, most practical antennas are unbalanced by their
surroundings, even if we attempt to make them a balanced antenna and
feed them with 2-wire line and a so-called balance tuner. It is that
imbalance that causes common mode current. If the imbalance is
relatively small, and if the antenna is resonant and fed with coax, we
can choke it effectively.
