Few ham antennas are perfectly balanced -- they are often unbalanced by 
their surroundings. For example, ground slope, unequal heights of the 
two halves, other conductors around the antenna, even vegetation. And 
yes, all elements of the antenna system, including the feedline, the 
antenna, and matching at both ends, contribute to the balance of the SYSTEM.

THAT'S why it's wrong to talk about "balanced line," using "parallel 
wire" or 2-wire" line instead.
