Actually, ghosting is path problem where two signals time lag
(reckoned by distance traveled by different paths - at least 100s of
meters if not km) present the viewer with two pictures.
The impedance variation gives rise to color distortion, smearing, due
to relative phase shift and/or BW clipping.

The "ghosting" I'm talking about is a very close-spaced ghost, perhaps
1/4 inch or less on the screen. It can definitely be caused by a poor
antenna. I used to install TV antennas for a living, trust me on that.
If you're talking about a ghost spaced several inches away on the
screen, then your statement above is correct.
