make, Cecil? One that is short compared to the delay.

What difference would it make if the frequency of the
pulse is far removed from the operating frequency?
What difference would it make if the frequency is far
above the self-resonant frequency? What difference
would it make if the inductance is completely
swamped by the capacitance? Shirley, you jest.

What's different about the 'situ' during
steady state that causes electromagnetic fields to propagate differently
than at other times?

They don't propagate differently but how does one separate
the forward wave from the reflected wave on a standing-wave
antenna? If you can do that, you will have solved the
measurement problem.
