Richard,
The round trip time on the transmission line is 1uS+, and the period
of the highest modulating frequency is 0.2uS, so transient
performance of the line is very important.

Sorry, sir, but quite a few decades of experience in the analog TV
broadcast industry show otherwise (not to mention an accurate
theoretical analysis of this condition).

Richard, I don't think you read my words. You are disagreeing with my
proposition that transient performance of the line is very important (in
the TV example you cited).
