No mysterious "reverse r-f energy" is needed to explain this well-known
and well-understood phenomenon.

The quote above reads as though the existence of reverse (reflected)
r-f energy is being denied.

For skeptics, the link below leads to a field report showing a measurement
of the reflection of a narrowband r-f pulse by an analog broadcast TV
antenna, back toward the source. The H.A.D. of the sin² pulse used
represents the shortest transition time that can be accommodated in a ~ 4
MHz transmission channel.

Note that the reflected pulse appears some 6.2 µs after the incident pulse,
which corresponds to a round trip through the ~1,525 feet of 6" OD, 75 ohm,
air pressurized transmission line leading to the antenna in this system.

The return pulse amplitude indicates a far-end match (elbow complex +
antenna) of about 1.05 VSWR (2.3% reflection).
