Reflection coefficient for total re-reflection

A re-reflection preserves the modulation content of the re-reflected

due to destructive interference does NOT preserve the modulation. In
fact, any differences in modulation between the two superposed wave
components would wind up incident upon the source.

Oh, yeah?

Simply, the conditions for steady state analysis are not satisfied by TV
bandwidth modulation on a long feed line.

This is the reason why some matching schemes that are quite suitable for
SSB telephony on feedlines of a few hundred metres are not used with TV
on long feedlines.
