Winding a 1:4 Current Balun with 15 turns. Post 797.
If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/IR-8T0QjUjM. In this video from N7JFP, we learn how to make a simple 1:4 current balun for connecting your rig to antennas using 300 ohm television twin lead, 450 ohm ladder line, or homebrew feed lines. Such antennas, used in conjunction with a 1:4 current balun and a well-made antenna transmatch (i.e. "tuner"), can give your dipole, vertical, or loop multiband capabilities. N7JFP uses this current balun on his 40 meter Delta Loop, which allows him to work stations on 20, 15, and 10 meters as well. Most of the components can be bought at the nearest home improvement outlet, neighborhood hardware store, or through amateur dealer outlets online.
