Ham Radio: Folded Dipole for HF.

Image
  Here's another "classic" HF antenna that's worth exploring--The Folded Half-Wave Dipole. In this video, Tim (G5TM) discusses the pros and cons of this unusual HF antenna.  The antenna is somewhat more difficult to build than the common dipole antenna and is not well-suited for portable operations. However, the high impedance of folded dipole allows the use of 300-ohm TV twin lead or 450-ohm ladder line as a feed cable...something you may want to consider if regular 50/75-ohm coax isn't availble. The folded dipole tends to be more broad-banded than the single wire dipole antenna. The folded dipole antenna once formed the foundation of popular roof-mounted television antennas in years gone by. This antenna is fun to build and can be an outstanding performer if it's designed properly.

  The Rybakov multi-band non-resonant vertical antenna is a popular choice for both home station use and for operations in the "field."  In this video, Tim (G5TM) discusses the pros and cons of the Rybakov Antenna, and adds some modifications to enhance the performance and efficiency of this easily-made antenna.   If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=PrBe9faqthM. Thanks for joining us today. Aloha es 73 de Russ (KH6JRM). Here are some comments from Tim (G5TM):   Developing the Rybakov Multi-Band non-resonant antenna into an even more convenient way to deploy it. This time, no ground radials and using the car as a ground/earth. Takes less than 5 minutes to deploy Connect with my channel by subscribing and commenting.
