Every one of us at one time or another has either asked or attempted to understand the science of antennas on handheld radios. This video, by a well known ham radio antenna manufacturer, simulates a quarter wave antenna, held at ear height and illustrates the gain. It’s a short video and doesn’t go nearly far enough, but it’s interesting and could be a starting point for more in-depth conversation.
