WebJan 27, 2003 · SWR (Standing Wave Ratio) is a measure of the antenna efficiency. The Standing Wave Ratio is equal to the ratio of radio and antenna impedances. This means that for a 50 Ohm radio, an antenna impedance of 75 Ohms will give a SWR reading of 1.5:1 (14dB return loss). What is a good SWR reading ? WebApr 4, 2024 · To fix high SWR on CB, follow the steps in the next section. 9. Shorten the Antenna. Reducing the antenna’s length is one of the most common solutions to minimize high SWR on 1 and 40. To make the antenna shorter, start by putting it in a stable position.

Don't worry about getting SWR as low as you can, … WebA high SWR on an antenna probably means that the antenna is not tuned to the frequency that is being used. This, in turn, means that the antenna has some inductive or capacitive reactance that is de-tuning the final amplifier. De-tuned final amplifiers draw far too much current and can burn up. take-off fuel
