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.

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.
