Webtom SWR scale. From here you can read the SWR for this load. The SWR is 1.6:1. Another useful attribute of the Smith Chart is called a constant SWR circle. The SWR circle contains all the possible combinations of resistance and reactance that equal or are less than a given SWR. The circles are drawn with a compass by using the distance from http://www.ve2azx.net/technical/RLBridges.pdf

WebFor an ideal system, voltage does not vary. Therefore, its VSWR is 1.0 (or more usually expressed as a ratio of 1:1). When reflections occur, voltages vary and VSWR is higher, for example 1.2 (or 1.2: 1). Increased VSWR correlates with reduced transmission line (and therefore overall transmitter) efficiency. Reflected Energy WebMay 29, 2000 · The vector network analyzer (VNA) is an essential tool for measuring the complex impedance of a circuit at a given frequency. The basic principles of operation … WebSWR stands for “standing wave ratio” and is a measure that can be used to tune an antenna for a particular frequency. The closer the SWR is to 1:1 at the designed antenna frequency, the better the antenna will receive (and transmit). In his video Adam shows how he measures the SWR of an ADS-B antenna which he has built and is selling. His ... psychology infant reflexes
