Jeff is right, inductance would be the correct term but you want a coil made
of wire...Well what do you call a strip line used in VHF & UHF & beyond in
Ham Transmitters...I'm referring to a straight piece of wire (strip line)
that is not a coil & has no turns....Now you have your answer, it is
possible & is done with no coils...Howard K0ACF

Microwave transmitters routinely use resonant devices other than coils
and
capacitors.

Yes. It was impossible to "make" the microwave frequency using coils.
Magnetrons are for it.

But are the modern radio waves (ham) transmitters without any coils?

Generally they have coils, but NOT Tesla coils, it would be possible to
not use coils, but it not usual. (Depending on what you call a coil,
inductance would be a better word, as this can be generated in ways other
than what would normally be termed a 'coil'.)

A coil is made of a wire.
Are "magnetrons" or simmilar device for yours transmitters?
