Antenna Designs, Reviews, and Tutorials

Long ago, Shortwave America promised an article on antennas. All of the projects, designs, reviews, and related items were simply too numerous to write just one piece on. Even a multi-part series would have been too large of a project. A more practical approach was needed, so, Shortwave America went scouting for everything and used the most practical information.

This guide is not intended to be the end-all, be-all of antennas because of all of the various designs out here, different emission types, different needs for antenna radiation polarization, and operator preference for minimum power usage. this is mostly handy for new Operators / SWL's, those who want or need a refresher, and those who want a nice resource for double checking their work.

Finally, the Shortwave America readers have a one stop resource for antenna knowledge similar to the more popular resource that was written for monitoring numbers stations. It's been quite a long time, but it's here now. Enjoy this resource to your heart's content! That why it's here!
