SWR Demystified: AD#28

SWR, or standing wave ratio, always comes up when discussing antennas and feedlines. Although it's by no means the most important element of antenna performance, it's the easiest to measure, and thus probably the parameter most talked about. This video explores SWR in some detail. Thank you for watching my videos! My channel, "Ham Radio Answers," is here to help you become an active, on-the-air amateur radio operator! I am unique in that I provide the only set of YouTube training videos that accompany the ARRL license manuals, section for section. I try hard to answer every Ask Dave question individually if I can.

Credits: Music (Sour Tennessee Red) courtesy YouTube Audio Library: https://www.youtube.com/audiolibrary/.... I often use graphics from openclipart.org -- a great source! I also frequently use photos and videos from http://www.nasa.gov. The GIF showing infinite standing wave ratio is from Wikipedia. The GIF showing 3:1 SWR is one I made using 32 images I created in LibreOffice Calc and combined using www.gifmaker.me.

I'm often asked what equipment I use to create the videos. The devices include the Panasonic HDC-TMT90 video camera, Tascam DR-05 audio recorder, Audio-Technica ATR-3350 lapel microphone, Sony Cyber-shot DSC-W560 digital camera, the Kodak Zi-8 video camera, my iPhone 5S, and Pentax K100D DSLR. Software used: CyberLink PowerDirector 13 on a Toshiba S55-A5294, also using Smoothdraw 4.0.5.0, FastStone Image Viewer 5.3, FastStone Capture 8.0, Audacity 2.1.1., and LibreOffice 5.0.4.2.
