Extra Class Lesson 9.1, Basics of Antennas, 11th edition. Post #1588.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=cNcTVWCEeU0. This is a must see video for those of you preparing for the Extra Class Amateur Radio License in the United States.  The video provides an excellent overview of basic antenna theory, including antenna radiation patterns, gain, bandwidth, and design features.  Dave Cassler (KE0OG) is an excellent teacher who clearly explains how antennas work and what is required to design them properly.  Review this video a few times before your exam...you won't regret it.
