This video contains the best explanation of how waves behave, what SWR is, and how impedance matching reduces energy loss/waste. I first saw this video when assisting with a ham radio licensing class and the instructor had this video on DVD. Thanks to Chris Andrews, N0CTA (a student in that class) for finally locating this online after a few years searching (off and on of course).
When is ARES useful?
Wilson County Amateur Radio Emergency Service is useful when normal methods of communication are overloaded, out, or otherwise insufficient to meet the needs of a relief response or to handle the health, safety, and welfare needs of your group or event. We also are available for events which provide us an opportunity to practice and hone our operating skills.
