I did not copy my statement. Vigor is defined in my "American College
Dictionary as: "1. active strength or force---".

A rod in free space becomes excited and accepts energy, which it must
re-radiate, when it is swept by a passing wave of its resonant
frequency. Its first resonance is near a 1/2-wavelength. At frequencies
slightly off-resonance, little current flows in the rod due to the
opposition of its reactance.

You may have seen a mechanical analogy in the vibrating reed frequency
meter.

What is the "strength" of an antenna?

What is the "force" of an antenna?

Is it the same as the "oomph"?

Units of force do not include Watts.

Units of force are such things as Newtons, dynes, poundals, pounds, etc.
