What is an SWR Meter?SWR MeterdefinitionA standing wave meter, also known as a standing wave meter, is used to measure the mismatch between a transmission line and its load (usually an antenna), helping technicians with impedance matching.SWRdefinitionThe standing wave ratio measures the ratio of maximum to minimum voltage or current along a transmission line, reflecting the efficiency of impedance matching and indicating the presence of standing waves.SWR formula and calculationVSWR can be calc

What is an SWR Meter?A standing wave ratio meter – also known as an SWR meter, ISWR meter (current “I” SWR), or VSWR meter (voltage SWR) – is defined as a device that measures the standing wave ratio (SWR) in a transmission line. The SWR meter indirectly measures the degree of mismatch between a transmission line and its load (usually an antenna). This is helpful to know the effectiveness of the impedance matching performed by technicians.SWR meter helps to determine how much of radiofrequency e
