I followed it accurately. If the antenna is resonant (frequency) the
impedance drops to a value which is dependant on distance from ground.
Away from resonance the impedance goes high. The impedance of a
random wire is largely a function of frequency.

Transmission lines have characteristic impedance, non-frequency
dependent. Antenna impedance (original question) does have a
frequency component.

A transmission line is not a generator.

Not for it's characteristic impedance. Does your coax have a different
impedance at different frequencies?

news Isn't there a frequency component?

The "Impedance" of a Random Wire Antenna is largely a function of :
- The Length of the Wire with respect to the Frequency Specified.

No. The length affects the reactance over frequency.

- The Height of the Wire above ground level with respect to the
Frequency Specified.

Yes. The height above ground and the wires diameter.

The height above the ground in wavelengths, which is frequency
dependent.
