Here are some comments from Scott (NB0W):
Close up details of how I built my 20 meter delta loop antenna. This antenna has worked well for the CW POTA activations I've used it on so far.
Materials Used:
The 12m carbon fiber poles came from AliExpress. There are many different suppliers/brands of them. I ordered these just before tariffs

While building, my thought with the plastic cutting board was for insulation, but the wire element doesn't really touch anything

4:1 Balun & Mast Clamps came from DX Engineering

The mast and support would be whatever works for your setup/vehicle/situation.
All the other hardware came from local sources (Tractor Supply, Ace Hardware), or already had on hand.
The majority of my adult life has been working as a cabinet maker so I do have tools which helps in cutting materials, drilling holes, etc.

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.

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. ...
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.
