So, a source exhibiting 200 Ohms Resistive feeding a 50 Ohm line that is then terminated in a load of 200 Ohms Resistive exhibits what SWR? Assuming a lossless 50 ohm line, the steady-state SWR is 4:1 no matter what the source impedance (assuming there exists a source voltage not equal to zero volts). Steady-state SWR in a lossless feedline is a constant fixed voltage ratio from end to end. -- 73, Cecil, W5DXP |
