The swr measures what
In radio engineering and telecommunications, standing wave ratio (SWR) is a measure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide. Impedance mismatches result in standing waves along the transmission line, and SWR is defined as the ratio of the partial standing wave's amplitude at an antinode (maximum) to the amplitude at a node (minimum) along the line. WebFeb 17, 2024 · An SWR meter is a device that measures the standing wave ratio (SWR) of a radio signal. SWR is a measure of the efficiency with which an antenna or transmission line radiates or transfers power. The higher the SWR, the greater the loss of power. SWR meters are used to tune antennas and transmission lines.
