The ratio of highest voltage on the line to lowest is the standing wave ratio.

The voltage standing wave ratio is then equal to:

Slotted lines are primarily intended for measurement of the voltage standing wave ratio on the line.

SWR (standing wave ratio) is typically 2:1 over the range of the design frequency to the second harmonic and 3:1 thereafter.

As a broadband antenna, the T2FD will normally display a reasonably low standing wave ratio across its entire frequency range.

The absolute magnitude (designated by vertical bars) of the reflection coefficient can be calculated from the standing wave ratio, :

It is a common misconception that a high standing wave ratio (SWR) per se causes loss.

The ideal dummy load provides a standing wave ratio (SWR) of 1:1 at the given impedance.

In terms of the voltage standing wave ratio (VSWR):

Return loss is related to both standing wave ratio (SWR) and reflection coefficient (Γ).

The ratio of maximum power to minimum power in the wave can be measured and is called the standing wave ratio (SWR).

The 'power standing wave ratio' (PSWR) is defined as the square of the VSWR.

A controlled cable characteristic impedance is important because the source and load impedance should be matched to ensure maximum power transfer and minimum standing wave ratio.

Standing wave ratio (SWR or VSWR) is a basic parameter that can be measured on a slotted line.

Voltage standing wave ratio (VSWR) measurements may be taken to ensure that a waveguide is contiguous and has no leaks or sharp bends.

Further criteria are operating bandwidth, gain flatness, stability and input and output voltage standing wave ratio (VSWR).

The degree to which the wave resembles either a pure standing wave or a pure traveling wave is measured by the standing wave ratio (SWR).

The mated pair of APC-7 connectors has a low reflection coefficient and low voltage standing wave ratio (VSWR).

To understand the standing wave ratio in detail, we need to calculate the voltage (or, equivalently, the electrical field strength) at any point along the transmission line at any moment in time.

A typical transmitter would not find that impedance acceptable and would deliver much less than 63 watts to it; the transmission line would be operating at a high (poor) standing wave ratio.

This is indicated by a finite standing wave ratio (SWR), the ratio of the amplitude of the wave at the antinode to the amplitude at the node.

Unlike an SWR meter which measures the standing wave ratio in the cable feeding the antenna, a complex-impedance antenna analyzer requires little or no transmitted power applied to the antenna.

The SWR meter or VSWR (voltage standing wave ratio) meter measures the standing wave ratio in a transmission line.

The impedance of a lossless transmission line may be neatly expressed in terms of the voltage standing wave ratio S at positions where there is a maximum or minimum of the voltage standing wave.

For stationary antennas, excessive amounts of ice can detuning the antenna to the point where its electrical impedance at the input frequency rises drastically, causing standing wave ratio (VSWR) to rise as well.
