You're asking the right questions, Paul. And balance is determined by 
the entire antenna system, not only the feedline and the transmitter 
(tuner). Most REAL antennas are unbalanced by their surroundings, and 
most REAL parallel-wire feedlines are unbalanced by their surroundings 
-- we have to get them through walls, for example.

There's also the matter of CAPACITIVE coupling through a transformer, 
which also couples noise across the transformer.
