Assume a 100+j100 ohm load and a 100-j100 ohm transmitter
directly connected with no transmission line. The system
is matched. Are there any reflections? Now install a
transmission line. Will an SWR meter read the same thing
in both cases?

What's the Zo of the transmission line? Is it sufficiently long to act
as a transmission line?

Cecil, methinks you posed an incomplete question :-)
