Dipole Antenna, back to basics-simple build

Image
  According to Mike (M0MSN), one of the simplest, most effective HF antennas you can build is the "classic" dipole antenna. In this video, Mike discusses the theory and practical uses behind this easily-made HF antenna.  Mike shows us a speedy and efficient way to make a fan dipole which covers a variety of HF frequencies without resorting to an antenna "tuner."

Here are some comments from Mike (M0MSN): Hello again, After many days off I am back with another simple Antenna Build. There is much to be said about a simple dipole antenna and much that is missed, so in this upload I try to bring the simplicity and speed of building a dipole and how to make it a fan of more than a single frequency, by turning it into a FAN Dipole. Just for fun Please subscribe and like. Cheers Mike - M0M...

The Helical Antenna

  Thanks to "FesZ Electronics" for this excellent introduction to "Helical Antennas." In this video, we get an in-depth discussion of Helical Antenna modes (normal and axial), radiation patterns, design and building guidelines, and other important characteristics of this popular antenna choice.

Here are some comments from "FesZ Electronics": #270 In this video I look at the main characteristics of helical antennas. These are some of the simples circularly polarized antennas that can easily be built by amateurs and are quite commonly used over a wide frequency range. I analyze the main constructive characteristics of such antennas and then perform a few experiments with a couple practical devices. Correction: at 3:00 the wavelength is c/f rather than f/c Antenna series:...
