standing wave ratioThe ratio of the amplitude of a standing wave at an anti-node (minimum) to the amplitude at an adjacent node (maximum). Note 1: The standing wave ratio (SWR) in a uniform transmission line is given by where is the reflection coefficient. Note 2: Reflections occur as a result of discontinuities, such as an imperfection in an otherwise uniform transm [..]

standing wave ratio[SWR] The ratio of the maximum (voltage, current) to the minimum (voltage, current) points of a transmission line. Indicates the impedance matching quality of the termination of the line. Standoff. A [..]
