Thanks to the "Wiltshire Man" for this simple, easily made 4 to 1 balun for multiband HF antennas. Here's how this radio amateur describes this project: I built this simple air cored balun in next to no time. No need to worry about toroids etc. It works from 3 to 30 mhz and handles 200 watts easy. If you use thicker wire it will handle a cool 1KW. ----------------------- For the latest Amateur/Ham Radio news and information, please visit these websites: http://www.HawaiiARRL.info. http://www.arrl.org. http://www.blurbrry.com/arrlaudionews/ http://www.hamradioupdate.com. https://oahuarrlnews.wordpress.com. https://hamradiohawaii.wordpress.com. https://bigislandarrlnews.com. https://www.eham.net. http://www.southgatearc.org.

Here is a simple, effective way to match your multiband HF antenna to feed lines using either 300 ohm television twin lead or 450 ohm ladder line.  These feed lines would then go into your antenna transmatch (i.e. "tuner").  According to "Wilshire Man", " I built this simple air cored balun in next to no time...no need to worry about toroids, etc.  It works from 3 MHz to 30 MHz and handles 200 watts easy.  If you use thicker wire, it will handle a cool 1 KW."  As some readers have pointed out, this device is a voltage balun and may exhibit greater losses than a current balun made from ferrite material.  None the less, if you need a 4:1 balun for emergency or portable use, this project could be what you're looking for.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds a
