The Doublet | Best Multiband Antenna?

-


 

I've always enjoyed making "classic" Ham Radio Antennas."

In this video, Tim (K5OHY) explores one of my favorite HF multiband antennas--the Doublet.

According to Tim, the easily made Doublet is an excellent performer in the field and at your home station.

Time reviews the pros and cons of this versatile HF antenna and provides some modeling guidance.  He conducts a live test of this design during a recent QRP operating event.

  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.

  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.
