We are not concerned with the characteristic impedance of the wire
antenna. We are concerned with its RF impedance as an antenna, not a
piece of metal.

Resonance is defined as when the reactances neutralize each other, a
very frequency dependant characteristic give a fixed size conductor.

You are confusing the wires intrinsic impedance to its reactance to some
specific frequency of signal energy. This is a common mistake.

The characteristic impedance is where the center of the antenna's
impedance spiral is. That's a good choice for a matching impedance if
what you want is a broadband antenna.
