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:...
