Also, the ghosts should be multiple... In the example cited of 2 uS
delay, there should be a ghost every 2 uS across the screen, albeit
each subsequent ghost a fixed number of dB weaker that the one
before due to the % radiated (plus line losses) for each round trip...

The ghost image needs to be at least 1% of the peak amplitude possible for
the primary video signal before it becomes noticeable So in order for the
2nd and successive ghosts in my example to be visible to a TV viewer, the
reflection producing the first ghost would be so objectionable that a TV
station would not tolerate it, and fix the problem.
