I'm, for now, interested in HF bands with, for now, a long wire.
I'm therefore aiming for a 9:1 balun.
This is pretty late in the game, but it also depends on your receiver. Ham radio equipment is (usually) designed for 50 ohms, but SWL type radios typically had higher impedance antenna inputs.
Are you sure you really need a transformer (you're describing a transformer, not a balun - as has already been mentioned).
