SWR, the radiation resistance We often hear the expression 'my antenna displays an SWR of such a value'. Amateurs saying that do not understand how work their antenna and its associated feed line. The SWR is not an antenna property but rather a property of the transmission line. An antenna displays only an impedance (and other ) that varies with the frequency. Contrary to the idea sometimes expressed by amateurs, the impedance matching of your antenna has few effect on your signal and a mismatch does not create RFI.

The SWR, that stands for Standing Waves Ratio, expresses the impedance matching between your feed line (or the transceiver) and the charge (the antenna), in other words the radiation resistance of your antenna system to not confuse with DC resistance. Impedance of an antenna refers to the ratio of the voltage field to the current field flowing within an antenna. On a well tuned aerial which feed line displays an SWR ratio of 1:1 all the RF energy is transmitted from the RTX final amplifier to the antenna tuner and then through the feeder to the antenna. In this configuration the current is equal at any point of the line and your antenna works properly. If the SWR increases for any reason, stationnary waves appear; in HF that means that a part of the RF energy you sent to the charge is waste as heat before reaching the antenna, mostly in the feed line. Note that using very low loss feed lines, in HF and in a lesser extent in V/UHF, this waste due to a high SWR is very weak.
