I'm liking my current forcing, 1/4 wavelength and 3/4 wavelength coaxial baluns
more and more!

>For example, there is a limited range of conditions where an air-core
choke balun reduces common mode. Outside of that, the air core choke can
increase common mode. No one mentions that in articles about winding
air-core chokes.
>Our largest resource on common mode and baluns never looked once at
common mode system impedance, and right at the very start showed a
gross misunderstanding of the cause of unbalance. Virtually all that
book looked at was SWR and power under matched conditions with floating
loads. We worry about exact numbers being within 10%, while we assign
numbers to systems that are over the place. In the meantime, important
basics are completely overlooked or misunderstood.
