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. -- 73, Cecil, w5dxp.com "Halitosis is better than no breath at all.", Don, KE6AJH/SK |
