Antennas 101 / How does an antenna work. Post 1801.

This video from "0033mer" does an exceptionally good job of explaining basic antenna theory in terms anyone can understand.  The use of a bagel and a small "rubber duck" mobile antenna to illustrate radiation patterns is a stroke of genius.

The video describes how antennas work and the properties of different configurations, including the common dipole and 1/4 wave monopole.  With this basic knowledge established, the video shows you how to build your own monopole antenna.  This video is a simple, accurate, and practical introduction to antennas.  The video would make a great presentation to an amateur/ham radio license class.  Place a copy of this well-done program in your ham radio reference library.
