WebSWR in this range is usually caused by a poor mounting location and/or a poor choice of equipment for your specific vehicle. To troubleshoot, you'll likely need to move the mounting location and/or use a more suitable antenna. SWR 3.0+: Performance will be severely affected, and you're likely to damage your radio with extended transmission use. WebThe definition of "standing wave ratio" (SWR) is the ratio between the maximum voltage (or current) found at any point along the line to the minimum value found at any other point along the line. Sometimes the term VSWR is used to explicitly denote the voltage ratio. The value of this ratio is directly related to the ratio of Z 0 to the ...

WebSWR: SWR stands for Standing Wave Ratio. It describes the voltage and current standing waves that appear on the line. It is a general description of current and voltage standing waves. It is usually used in conjunction with a meter used to detect VSWR.
