Default Transmitter Output Impedance

Richard, I must totally disagree that the same degree of mismatch
occurs at the tx output as at the dissipative load, the antenna.


May I suggest that we simplify the example by removing the tuner from
the discussion?

100w--+----1/4WL 100 ohm feedline----200 ohm load

Same conditions as before. The voltage reflection coefficient at the
load is 0.3333. The power reflection coefficient at the load is
0.1111. A 50 ohm Z0-match exists at point '+' without a tuner. No
reflected energy reaches the source.
