Webstanding-wave ratio (SWR, VWSR, IWSR): Standing-wave ratio (SWR) is a mathematical expression of the non-uniformity of an electromagnetic field ( EM field ) on a transmission line such as coaxial cable . Usually, SWR is defined as the ratio of the maximum radio-frequency ( RF ) voltage to the minimum RF voltage along the line. This is also ... WebJul 11, 2024 · The antenna is horizontal, approximately 19 feet above ground, fed by a 100 foot RG-58X feedline. As you can see from this spreadsheet, my SWR is consistently higher (with one very odd exception in the 12m band!). The manufacturer used a RigExpert AA-30 for SWR readings, I used a RigExpert AA-54. (The 2.85 SWR I measured was drifting …

Diese wurden alle ausgestrahlt in der täglichen TV … WebSWR is, thus, the ratio between transmitted and reflected waves. A high SWR indicates poor transmission-line efficiency and reflected energy, which can damage the transmitter and decrease transmitter efficiency. Since SWR commonly refers to the voltage ratio, it is usually known as voltage standing wave ratio (VSWR). VSWR and System Efficiency WebApr 10, 2024 · 4.
