5/8th wave 10 meter vertical antenna build

-


 

If you need a bit of gain (approximately 3dBi) for your next 10 meter band antenna, please consider this vertical antenna project from Ian (G0CNN).

In this video, Ian converts an old 5/8 wave CB antenna into a 5/8 wave 10 meter band antenna. The "reengineered" vertical is easy-to-make and performs very well with its new identity.

Ian takes us step-by-step through the entire process, which uses locally available materials and some simple tools found in your ham shack.

Here are some comments from Ian (G0CNN):

Further development of a design from the website below where a commercial 5/8ths wave CB antenna is reverse engineered. This enhanced model is tuned specifically for the 10m amateur band and also adopts a ferrite choke, which is an improved option over the air-wound choke which is also shown in the build. The parts for this simple DIY build probably already exist in your shack? If not, they come to about £5 for the air-wound choke model, or about £10 if you go for the ferrite choke model. A list of parts: Main Antenna = 3.5m RG58 coax + 3.25m of insulated wire Air-Wound Choke = 3.6m RG58 coax (or) 9 Turn Ferrite Choke = 73cm RG58 coax (+ the ferrite) - a 12 Turn on a 52 or 61 core will use a little more coax, say 1m in total. Matching Stub = 71cm Westflex 103 coax Original CB antenna article: https://radioaficion.com/cms/sirio-ga...

I built a US military TEFV HF Field Antenna

  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.

-
Image
  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.

Building an off-center-fed (OCF) dipole

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. ...
