SMALL & EXOTIC ANTENNAS
A Compendium of Evaluations
Learn the Real Performance from the Experts!
ELIMINATING RUMORS & CONFUSION
here
is a great deal of confusion about the emerging technology of compact antennas and those
that claim to be highly efficient compacts. There are numerous ways an antenna can radiate
and perhaps mislead as to its true performance. Remember also that an antenna is by nature
a "coupling device" and some do it better than others. To get at the truth about
the performance of an antenna, certain clinical test conditions must be met and real
measurements must be made. The "antenna" must be tested while isolated from
other influences that would distort its true performance.
Adding to the confusion about these compacts are the uninformed discussions, or just plain unfounded rumors. It is quite amazing how long claims about performance are allowed to go unchecked and continue to perpetuate in the field of antennasnot just compacts, but many conventional antennas as well. This is really a caveat emptor business. It doesn't need to be so because it's not all that hard or expensive to do sufficient measurements to check those claims. Forget QSOs or just A/Bthats not meaningful enough.
REAL PERFORMANCE, NOT JUST THEORY
If one is a radio amateur who possesses a device that consistently does what one
wants, then that may be fine. However, it does not mean a whit as to the REAL performance
of that device. The device may actually be radiating from the feedline and/or coupling and
amplifying its signal from the surroundingsthat is NOT the antenna you thought you
bought and told was a compact!
The statements here are not meant to imply that all claims are false or even distorted by the promotersonly that many of these claims are just taken for granted and may remain unchecked. If the claims are left to stand long enough, then they tend to become "fact" and any real basis for it long lost over time. The Isotron is one good example of this. This device had been around for more than two decades before it was expertly investigated by one of our writers and the results reported by antenneX. Until that happened, the device was shrouded in mystery and rumorswell, no longer!
ISOTRON EXPLAINED
We mention the Isotron only because it has been around the longest without any
visible published test of claims among the group of small antennas analyzed in this book.
The Isotron is only one of 12 different groups of compacts that have emerged
within the past 20 years analyzed in this special 470-page book Small and Exotic
Antennas. This book has been needed for a long time and is especially aimed at
reducing the confusion about the most talked-about compacts. It contains 50 chapters of
the theory, construction, use and test performance of some of the most popular compacts.
So, if you are considering any of these compacts as a solution to an antenna need but
wonder about their performance, this book is for you. At the very least, you will be
better informed before making a decision and spending your money and valuable time.

CONTENTS
Even if you are not considering a use of one of these devices, this new book makes
an excellent compendium of knowledge about how the antenna technology has evolved over the
past 20 years. There is no other book like this book and it can fill a very large gap in
your library! One look at the list of contents below shows just how large a void it fills
about the current technology emerging in a myriad of concepts to shrink the present
antenna designs.
