Default balun spec depending on coax impedance


Dear all,

Usualy, people use 9:1 balun to connect a wire or dipole antenna to a 50 ohm coax.

If I use a basic TV coax (75 ohms) I suspect I will need a 6:1 balun instead. If
so, how many turns of wire should I use for primary and secondary windings ?

I don't know the impendance of the antenna connection of my radios (ATS 909 +
ICF SW100), so I intend to give a try with the coax I have in hand.

Thanks in advance for your help,

Charly
