A mind experiment into the world of Electro - Magnetics. Part 6

In this series of screen shots I show a transmission line with different feed Z and load Z.

What effect does matching the load Z to the feed line Z have?

What effect does lowering the generator Z have?

Consider R1 as an antenna, when the signal is radiated (absorbed by the load) we see no reflected signal and the generator can handle more power. The rule of thumb often quoted is for maximum power transfer we need to match the load to the generator. This is true BUT the generator drops half the power.
 Food for thought.
