Antenna Briefs #1 - Frequency, Wavelength, and Size

This is the first in a series of videos on antennas and how they work. It is based on and supports a university course, but covers material without any deep math. In Episode 1 we overview key elements of radio antenna operation and signal propagation. We start with the first antennas created by Hertz and proceed to demonstrations with modern antennas - focusing initially on dipoles. Additional types including loops, monopoles, and dish antennas are covered as examples of real-world antennas and are presented across the frequency range from 1 MHz to 40 GHz. The key takeaway is the formula for wavelength and how it relates to frequency antenna size (and directivity).
