Do you want to understand how a Yagi antenna works?

 

 

What You Will Learn in This Week's Podcast:

In this episode, Phil explains the elements of a Yagi antenna, what they’re used for, and even how to build your own.

 

  • Shintaro Udo and Hidetsugu Yagi created the antenna.
  • A Yagi antenna is a directional antenna with at least two elements, usually three, mounted on a boom.
  • The main element is the boom, where everything else is mounted.
  • A Yagi usually includes a driven element, a reflector element, and a director element, all mounted on the same plane.
  • The driven element is the main element, and it is what your feed line is connected to.
  • Next, behind the driven element, you have the parasitic element called the reflector, and in front, you have the director element.
  • The different elements are positioned to interfere with each other in a way that enhances the radiation and increases the directivity of the antenna.
  • The longest element always sits behind the driven element, and that’s how you know which is the front and back.
  • A Yagi can be used to pick up signals far away from you
  • You can use a Yagi antenna to try to overcome simulcast issues.
  • Yagi antennas are typically built for a very small range of frequencies.
  • You can get a cross-pole Yagi antenna, which is very popular with amateur radio and using satellites.
  • It is possible to build your own Yagi antenna with some basic materials.
