SWR & Return Loss Simulator Interactive RF Transmission Line Visualizer How to use this simulator: In a real radio system, the SWR (Standing Wave Ratio) depends on how well the antenna is tuned, not on transmitter power. Adjust Antenna SWR to simulate antenna matching and observe reflected power. Change Forward Power to test different transmitters — SWR remains constant while reflected power scales automatically. SWR METER 1 1.5 2 ...
