#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:
Ground Plane - • The Ground-Plane Antenna
Sleeve Dipole - • The Sleeve Dipole Antenna
Polarization - • Analyzing Antenna Polarization
