Ham Radio - Building a 4:1 balun

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=l5rLI8FpM9g.

If you use antennas with balanced feed lines, you'll find this quick and easy 4:1 balun designed by Kevin Loughin (KB9RLW) a good way to keep excessive SWR and RFI away from your HF transceiver.

Kevin does a good job of taking you from basic theory through final construction.  Most of the parts can be ordered online or found in your station "junk box."  This project would make an excellent presentation for your amateur radio club or for an amateur radio license class.

Although 4:1 baluns can be bought from a variety of suppliers, why not make one for yourself?  The process will be educational and fun.
