t_12.jpg (1082 bytes)here is a renewed interest in low frequencies due to changes in radio technology and regulations. Radio Amateurs may shortly receive a portion of the LF band, something that is beyond modern "ham" experience. Low cost wide area GPS error corrections signals may be broadcast on LF. Low cost terrestrial navigational back up signals also have the close interest of government agencies.

This article is just one particularly interesting chapter from a book from the BookShelf at antenneX about economical low and medium frequency antennas. The specific chapter here covers the practical aspects of vertical antennas, one of the most popular forms of antennas in this frequency range. However, there is much more covered in the book such as "Tee" and "Ell" antennas, practical matters such as signal reductions due to "corona" discharge and resistive losses, grounds, and especially mathematically estimated coverage of the station using different antennas. The book also has CAD drawings which may be modified and used for your own projects at great savings to you.


ABOUT THE AUTHOR
Robert is a physicist, engineer, and senior member of IEEE. He spent his career designing and supervising the installation of such antennas. Now retired, he shares with you the wisdom of hard-earned experience as an engineer with hundreds of low and medium frequency antennas to his credit and explains how to build good, effective, simple, low cost, long range antennas. he has been employed by the FAA, Voice of America, Martin-Marietta, Comsat, RCA, and DoD working in 21 countries.

He has handled government and civilian antenna projects in North, Central, and South America. His radio station projects have included Europe, Africa, and Asia. He personally built some of the first U.S. satellites. Mr. Wilson has been on the staff of the University of Colorado and Wyoming. Robert also attended the University of Alaska, Allegheny College, University of Colorado, University of Iowa, Lake Forest College, University of Maryland, and Rockford College. In addition he is a helicopter pilot, a ship radio officer, and a long time radio amateur with the call AL7KK. He now lives with his wife on a remote Alaskan lake.

Further, it has the fonts embedded into the article, especially important when using a character set that may not be on the reader's computer, such as the Greek symbols used for equations. So, the reader can save and print the PDF article totally intact exactly as it was originally intended.

Other important features are, with Acrobat Reader, the reader can magnify (zoom in or out) the article to many different levels so that those superscripts or subscripts can be seen with total clarity. And if the reader wants to, the article can be rotated making it easy to view diagrams from different angles!

THE WHOLE BOOK
This book by Robert is packed with illustrations in the form of engineering drawings. Most are made available on the CD-ROM in their native CAD engineering drawing formats allowing them to be loaded in your computer for customizing to your own design. Also, many of the drawings are provided in three different formats depending on your needs for clarity of the details. The drawings are to scale.
