Cubical Quad Antennas Volume 2

Here it is! Our much-requested release of VOLUME 2 of this new two-book series by L.B. Cebik. The popular Volume 1 in this pair reviewed existing quad designs and uncovered a number of factors that have not been fully appreciated. In this second volume, these factors lead to a rethinking of quad design and to some total redesign of monoband quad arrays. Among the factors influencing the rethinking of quad design are these: the relative narrow-band properties of the quad, the critical dependence of quad design on the diameter of its elements, the requirement for more spacing between quad elements to achieve optimal coupling relative to linear elements, the need for elements as thick as those used in Yagis if that quad is to net its theoretical gain advantage over the Yagi, and the relatively rapid rate of change of reactance across the quad operating passband. Volume 2 of this series results in computerized monoband quad design programs for 1 to 4 element arrays, as well as in a consideration of larger designs, narrow-band design, VHF designs, and factors influencing the elevation patterns of quads.

Considered an expert on antennas, 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 state 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. Volume 2 picks up where Volume 1 leaves off and considers other ways to design the Quad and further optimize its potential. This 240-page book is fully illustrated with over 200 sketches, graphs, modeling exercises, antenna patterns and some useful GW Basic utilities.
