Swr to high

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.
