What is Standing Wave Ratio (SWR) and how does it impact your amateur radio antenna system? Is there really such a thing as “perfect” SWR and does it really matter? DX Engineering’s Michael Murphy, KI8R, covers the basics of SWR, including reflected power; factors that can influence SWR readings, such as lossy coaxial cables; the importance of measuring SWR at the antenna; and some of the myths and misinformation surrounding this widely used measurement in ham radio.
