WebJul 7, 2024 · What SWR is too high? For instance a SWR too high (over 3:1) all over the band can be an indication of a bad part or junction, poor ground or poor location. An SWR too low over the whole band (1:1 for all 40 channels) can indicate a low efficiency antenna or lossy component. Safe operation of your CB should be with an SWR of 2:1 or less. WebHere's a step by step process for setting or tuning the SWR on your CB antenna: Check your SWR meter : Write down the SWR reading on channels 1, 20, and 40 based on the instructions above. Adjust your antenna: If your SWR reading is higher on channel 40 than it is on channel 1, lower something on your antenna.

"WebThe return loss of a system is defined as the ratio of incident power to reflected power and is measured in dB. High return loss results in low reflected power, so high return loss is desirable for a system. VSWR means that the ratio of the maximum voltage to the minimum voltage in the standing wave pattern along the transmission line. " - Swr to high

WebUse a length of coax that is electrically 1/4 wavelength. For mid band 20 meters, that will be 14.175 MHz in the US. A quarter wavelength will be (300/frequency [MHz])/4 or (300/14.175)/4 = 5.29 meters = 17.35 feet. Now typical RG-58/U has a Vf of 0.66 nominal. 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 ?
