Simple Ham Radio Antennas--Winding a 1:4 Current Balun with 8 turns. Post #903.


If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=AJHfzeqaW5U. Nicely done video from N7JFP on winding a simple 1:4 current balun. For this balun, he used a single torroid core T-130-2 and two sets of 18 gauge copper wires. Each side of the torroid has turns of wire.  The balun covers 14 MHz through 54 MHz and would make a good foundation for a balanced antenna transmatch (i.e. "tuner") using 450 ohm ladder line or 300 ohm television twin lead for an antenna feeder.  A good project for a rainy evening.
