The Doublet | Best Multi-Band Antenna?

-


 Here's a "classic" ham radio antenna you can build at home with locally available materials.  The Doublet Antenna using balanced feed line and a sturdy antenna transmatch (tuner), can cover several amateur radio bands.

In this video, Tim  (K5OHY) provides you with all the information you need to design, build, test, and use this versatile 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.

  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.

The Doublet Antenna: The Best Portable Multiband Ham Radio Antenna?

-
Image
  According to Time (G5TM), the "classic" Doublet Antenna may be "the best portable multiband Ham Radio antenna." In this video, Time explores the pros and cons of this simple, effective HF antenna. The doublet is easy to set up, deploy, and use in a variety of field and home station environments. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=3HDWPprOKFk. Thanks for joining us today. Aloha es 73 de Russ (KH6JRM). Here are some comments from Tim (G5TM). At last I got to try an antenna for portable HF that I have always enjoyed using in a compromised position at home. This time I had the space to properly deploy a 66ft (20m) Doublet Antenna and I WAS NOT DISAPPOINTED! Join me as I put this classic multi-band antenna through its paces, whilst showing how I put it together and tuned it. As well as showing its on-air performance.
