If a 50 ohm generator is connected to a 50 ohm
resistor (or resistance), the maximum possible
power is delivered to the load.
If the load is greater than or less than than 50
ohms resistor (or resistance) the power delivered
to the load is less than the maximum possible.
Unfortunately, the use of the term "Reflection Loss" to descibe performance
of amateur feedline + antenna systems at HF merely adds to the confusion.
"Maximum Available (or possible) Power" delivered to the load occurs only
when there's a "Conjugate Match" between generator and load.
But a Conjugate Match does not exist. It cannot even be assumed. For the
simple reason the internal impedance of the generator is never known. And
it wouldn't make any difference to how the system is set up and operated if
Even the generator (transmitter) designer doesn't know what the internal
impedance is. He couldn't care less. It can vary all over the shop depending
on what the load impedance is.
