I have been using balanced line for many years and am convinced of its
virtues, particularly since I use a single tuned doublet for multiband
use.

The key to using balanced line is to know what impedance you are dealing
with looking into the feedline. If it's too high, baluns don't work. If
it's too low, tuners don't work. You can always measure the impedance
but I have found that EZNEC gives a close enough approximation to the
feedpoint impedance that you don't really need to measure it. Some of
the principles are explained on my web page under "No-Tuner All-HF-Band-
Antenna".
