The antenneX CFA Series
The First World-Wide Published Series
The Claims of an Amazing Antenna Concept!
his series of articles
introduces a completely new concept in antenna theory. In fact, many say this is the most
important development relative to antennas in this century. It is so pervasive that a
series of articles are required to cover the concept and its applications to the depth and
extent it deserves. This is the first major publication about the Crossed-Field Antenna
(CFA) and probably the most inclusive collection of articles anywhere in the world! Most
articles are written by the co-inventors, Dr. Kabbary of Egypt, Maurice Hately, GM3HAT,
and Dr. Stewart, MM1DVD of Scotland, so you get first-hand information in this series.
What is different about the CFA? As an example, a CFA only 21 feet (6.5 m) tall, located at Tanta in the center of Egypt, provides AM broadcast service at 1.16 MHz (258 Meters) to millions of people from Cairo north to the coast. Certified measurements provide evidence that this small CFA produces a radiated signal almost 6 dB stronger than the previous 1/4 wavelength vertical broadcast tower which was 211 feet (65 Meters) tall. To express the performance a different way >> with the tall tower, a 100,000 watt transmitter was required for the desired coverage. With the miniature CFA the same coverage was attained with the transmitter power reduced to 30,000 watts.
