Voltmeters

The standing wave ratio (SWR) meter, or voltage standing wave ratio (VSWR) meter, measures the SWR of a transmission line. Use an SWR meter to document and log the degree of mismatch between a transmission load, usually the radio antenna, and its line. SWR meters measure the effectiveness of a transmission’s impedance matching performance. Use a directional SWR meter to measure the magnitude of forward and reflected waves, and an SWR bridge to determine the presence of a low standing wave ratio. Use a citizens band (CB) SWR meter to collect information from CB radio equipment. We sell new, used, and refurbished SWR meters from the leading brands.
