What I have failed to see in this thread is that the *wire* in a proper
"balun" (more properly a common mode choke) is a transmission line,
That transmission line can be two conductors side by side, or it can be
two twisted wires, or it can be coax or any other type of transmission line.
Its job is to block RF Current from flowing on the outside of the coax
shield. It is not a transformer, but a choking impedance.

A bal-un is a transformer. Technically, it has two windings on a
ferromagnetic core material which for RF is typically some flavor of
ferrite, usually in the form of a toroid.
