Volume 1: A Review of Existing Designs

L.B. Cebik, W4RNL

antenneX Online Magazine proudly introduces its publication and release of this new book by L.B. Cebik. L. B. has published over a dozen books, with works on antennas for both the beginner and the advanced student. Among his books are a basic tutorial in the use of NEC antenna modeling software and compilations of his many shorter pieces. His articles have appeared in virtually every amateur radio publication, with translations of some into several languages. Retired Professor from the University of Tennessee at Knoxville, LB is Technical & Educational Advisor to the ARRL.

As stated by this popular antenna expert, Cubical Quad Antennas have languished in a limbo between excellent user reports and a mixture of myth and fact about how they perform. This 2-volume series attempts to clarify some aspects of quad array performance and to codify some basic elements of quad design. Volume 1 begins with a necessary review of existing quad arrays, ranging from basic 2-element monoband beams to large multi-band designs. Throughout, quads are analyzed using current method-of-moments computer techniques to determine their HF characteristics: the goal is to find the actual bandwidth of basic performance parameters, such as gain, front-to-back ratio, and feedpoint impedance. The analysis attempts to isolate basic properties that affect overall quad performance. As well, various common point and individual element feed systems are analyzed to show their effects on performance. Full dimensions appear for each quad design, along with antenna model descriptions for those wishing to extend the analysis. Each chapter in this 220-page book is fully illustrated with sketches, graphs, and antenna patterns. There are 125 of these illustrations plus over 80 Tables about performance, dimensions, and parameters for modeling exercises. To see a Review of this book by Dan Handelsman, N2DT, click here.
