I'd like to make one but just can't find a decent reference. Go to the following webpage and order item #1542 for $3.00. You'll receive three T-43 ferrite toroidal cores measuring 1/2-inch in diameter. You'll need one core to make the balun. http://www.universal-radio.com/catalog/misc/amidon.html You can get the wire for winding the balun at your local Radio Shack. It comes in an assortment of three sizes for $4.99, - catalog #278-1345. - Here's the online catalog page for the wi - - http://tinyurl.com/2fws6t RadioShack Catalog # 278-1345 315-Feet of Magnet Wire - Set of Three Spools http://www.radioshack.com/product/in...ductId=2036277 1 - 40-Foot Spool of 22-Gauge Magnet Wire 1 - 75-Foot Spool of 26-Gauge Magnet Wire 1 - 200-Foot Spool of 30-Gauge Magnet Wire When you have the toroids and wire, get back to the group here and we'll tell you how to wind the balun and/or refer you to a webpage on how to do it.
