Ham Radio: Doublet Antenna & Coax.

-


 

As you build your "classic" doublet HF antenna, what kind of feedline do you prefer?  Coaxial cable or "LadderLine?

In this video, Tim (G5TM) discusses the pros and cons of doublet antenna feedlines.  Although the traditional doublet antenna used a balanced feedline measuring approximately 600 ohms, current designs of this familiar HF antenna can use 450 ohm (ladder line), 300 ohm (television twin lead), and even coaxial cable.

Tim does a good job of explaining the capabilities of each feedline, so you can choose the option best suited for your operation.

  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.

Ham Radio T2LT Antenna for 10m DX (or other bands).

-
Image
  If you want a low-cost, single band DX antenna for the 10 meter Amateur Radio band, please consider this T2LT (terminated folded dipole) design from Peter Waters (G3OJV). You can make this HF antenna from locally available materials. The T2LT is an excellent HF antenna for both portable and home station use.
