In radio engineering and telecommunications, standing wave ratio (SWR) is a measure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide. Impedance mismatches result in standing waves along the transmission line, and SWR is defined as the ratio of the partial standing wave's amplitude at an antinode (maximum) to the amplitude at a node (minimum) along the line. WebApr 3, 2024 · * Well, it will work on 60 meters, if you use a 76′ length of the 420 ohm window line; SWR is below 1.5:1. Note that the SWR values in the above charts are at the antenna. …

WebOct 2, 2024 · For best results you should account for feedline loss, poor SWR, etc. At VHF/UHF frequencies, the feedline loss with coax can be significant. For example, transmitting 100W into 80 feet of RG-8X coax to an antenna with an SWR of 1.4:1 at 146.52 MHz will result in only 46W of actual power at the antenna.
