SWR is short for “Standing Wave Ratio,” a measure of how well the antenna is performing. Most problems with the antenna or antenna cable will show up during an SWR check. A poor SWR is caused by the antenna, the antenna cable, or a poor antenna installation. Poor SWR is not caused by the radio. Since the SWR is a function of the antenna system, changing radios will not affect the SWR.
