How to build a 4:1 balun for HF Antennas

-


 One of the most useful antenna accessories these days is the basic 4:1 balun or matching transformer.

This device is especially useful for HF loop antennas, where the impedance hovers around 200 ohms.

Steve (K4S) does an excellent step-by-step tutorial on how to build this handy antenna tool.

  If you want to experiment with unconventional antenna designs, please consider adapting US military HF antennas.  These antennas are easy to build and perform well on several amateur radio bands. In this video, Walt (K4OGO) builds a Terminated End Fed V Antenna (TEFV).  The antenna is broad banded, requires no antenna "tuner", and covers frequencies from 1.8 to 30 MHz.

How to turn your fence into a Ham Radio Antenna.

-

  Here's another way to operate your ham radio station without nosy neighbors complaining about the visual impact of your current antenna system. In this video, Danny (KD5W) shows us how to use your property fence as super stealth HF antenna.  You can find most of your materials at the nearest hardware or building supply outlet. Many operators call this project a "Fencetenna"--something you may wish to use if no other antenna design is available.

Thanks to John (W5ODJ) for this variation of the popular Off-Center-Fed Dipole Antenna (OCF). The antenna is easy to build and uses a 4:1 balun to cover the 80m, 40m, 20m, and 10m Amateur Radio bands. Views expressed in this article are those of John (W5ODJ). Accessed on 12 January 2026, 2242 UTC. Building an off-center fed (OCF) Dipole – Loudoun Amateur Radio Group Please check email link or scroll down to read the full article.  Thanks for joining us today.  There is a video attached at the bottom of this post. Aloha es 73 de Russ (KH6JRM). --------------- Building an off-center fed (OCF) Dipole This type of antenna is a popular antenna design as the performance is very good across the HF bands and  requires little or no tuning . It’s a dipole fed off center with a 4:1 balun at the offset feed point. The antenna shown covers 80, 40, 20 and 10 meters. The formula can also be used to adjust the overall length to cover more or fewer bands and the resulting overall length. ...
