SWR is used as a measure of impedance matching of a load to the characteristic impedance of a transmission line carrying radio frequency (RF) signals. This especially applies to transmission lines connecting radio transmitters and receivers with their antennas, as well as similar uses of RF cables such as cable television connections to TV receivers and distribution amplifiers.

With the end of local pro sports coverage, FSN Chicago became mostly a feeder channel of the national network's entire schedule, some minor local and semi-pro teams, Midwestern outdoors programs, and sports rights and games from other college conferences of little interest to Chicago area viewers. In 2005, Cablevision bought all of FSN Chicago ...

An SWR meter does not measure the actual impedance of a load (the resistance and reactance), but only the mismatch ratio. To measure the actual impedance requires an antenna analyzer or other similar RF measuring device. For accurate readings, the SWR meter itself must also match the line's impedance (typically 50 or 75 Ohms).
