I have looked, but cannot find, some kind of formula to indicate the

Does anyone know where I might find that formula?

Hi Buck,

One does not normally build a frequency specific BalUn, unless it is
tuned transmission line based. As you are speaking in terms of
"turns," then that is obviously not the case.
