SWR or standing wave ratio is the ratio of the amplitude of a partial standing wave at an antinode (maximum) to the amplitude at an adjacent node (minimum), in an electrical transmission line. The SWR ...

Maximum transmission efficiency occurs when the load impedance matches the generator impedance. Engineers do this to eliminate standing waves, which can severely damage equipment. Transmission lines ...

Here’s a situation that creates fear and trembling: The engineer receives a call from the radio station: “The transmitter is off the air and there is a VSWR fault.” If the station is fortunate, the ...
