Balanced to Unbalanced WHAT ?

"Balun" is a contraction of "Balanced to Unbalanced "TRANSFORMER".

What is the transformation ratio of the W2DU "balun" and other
devices
which serve a similar purpose? Between which pair of impedances
does
it provide a match?

If YOU cannot provide answers then there are many old-wives who can.

There is a program named BALCHOKE available free from my website.

=====================================

To all and sundry,

My prediction about old-wives was correct.

Anybody who provided a transformation ratio or mentioned matched
impedances can consider him or herself to be an Old Wife.

It would be a waste of time for me to explain to Old Wives how the
uncertain impedance and length of line on the choke, combined with the
unknown impedances of its supposed terminations, actually works.

The impedance transformation ratio is entirely INDETERMINATE.

But it doesn't matter two hoots provided the length of line on the
choke is within certain limits. Only the choking action on
longitudinal currents matters.
