Equipment which measures standing wave ratio (SWR). See also [antenna-analyzer]. For questions about fixing “high SWR” problems, see [impedance-matching] instead.
A SWR meter is placed inline in a feed line to measure the standing wave ratio (SWR). It may be a separate unit or integrated in a transceiver. SWR meters often measure power as well; the “crossed needle” SWR meter displays forward and reflected power directly and the user reads SWR from the point of intersection of the needles.
Devices which produce their own test signal, and often measure more parameters than SWR, are antenna-analyzers.
