A transformer can step down as well as step up. Early crystal sets
stepped down antenna impedance to the low impedance of the rectifier
using a continuously variable autoformer (a sliding contact on a coil).
Position was adjusted for best results.

Wrong!

If a long wire antenna, regardless of Zo, is about 1/4 wavelengths long it
will have an input impedance less than 50 ohms.

A conventional balun will bring it down to much less.

And a conventional balun will not work the other way round.

For me, it has to be over a wavelength
before I'll call it 'long' wire... 1/4 wave is
*definitely* not a long wire, by any stretch
of the imagination.

That is the generally excepted definition.

On the contrary, it is the generally accepted definition.

You're saying that a 1/4 wave wire is 'long'?

No. Reread the thread.

I think reading lessons should be in your future. You're saying that you're
right and I'm wrong when we said the same thing?

No, I'm confirming your
statement (a longwire antenna has to be longer than one wavelength),
while at the same taking exception to what CW wrote.
