Some commercial G5RV antenna designs rely on the loss in a long coax feedline to bring their claimed SWR down in lieu of—or in addition to—an antenna tuner. WebAug 30, 2024 · The SWR reading must never exceed 3, otherwise the transmitter in the CB radio can overheat and eventually fail. Excessively high SWR can also cause other problems such as a squealing noise, or can cause interference with other electronic devices in the vehicle. An SWR below 2 is very good, and anything below 1.5 is excellent.
