How to make a 4 to 1 balun cheap and easy. Post # 594.

If you're having trouble viewing this video, please insert this URL into your browser search box: 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 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 are updated daily.
