With a reflected power of 10 watts, your watt meter will indicate 110 watts
forward, of which 10 watts must be subtracted from the reading to obtain the
correct value for forward power. When the 10 watts reflected power travels
back up the line to the antenna, it is radiated, BUT another 10 watts takes
its place and travels back down to the transmitter, which cancels out the 10
watts that just came up the line. The net power radiated will always be 100
watts in your case. The 10 watts just goes up and down the feed line, never
re-entering the transmitter. All this is going on at the speed of light.
There is a small loss in this case, due to the heating of the feed line. In
your "It seems to me" above, I am sure you are just pulling or legs, as this
is a ridiculous assumption.
