How to Build a 9:1 UnUn for Ham Radio Antenna


If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=mfnvqQeDLoQ. This post is number 2100 in a continuing series of simple ham radio antennas.

In this well-made video, "Tinker John" (W5CYF) guides us through the design, construction, and building of a simple 9:1 UnUn for use with long wire antennas. The device is cheap and easy to build--something John calls a "nice one-evening project." The finished project is suitable for both home and portable operations.
