Moxon Rectangle Notes by L. B.
Cebik, W4RNL, is the most complete study to date of this special antenna design, pioneered
by G6XN. The volume analyzes why the Moxon works as it does and supplies many practical
designs for amateur bands ranging from 80 meters through the UHF range. In addition, the
book provides both methods and means of designing a Moxon rectangle for virtually any
frequency simply by knowing the design frequency and the desired element diameter.
The volume begins by tracing the history of the Moxon rectangle and then supplies a complete analysis of its properties and its relationship to other 2-element arrays. In a special chapter, the author introduces three methods of computerized Moxon design: a GW Basic utility program, a NEC-Win Plus equation-based model, and a Windows program developed by Dan Maguire, AC6LA.
Practical Moxon designs begin in the lower HF region with wire rectangles for single direction use and for reversible beams, as well. For the upper HF region, there are rotatable aluminum tubing designs for home and field applications. There is a chapter on incorporating the Moxon rectangle into multi-band beams. In the VHF region, where the antenna is useful in both horizontal and vertical orientations, Cebik presents designs and applications making use of the Moxon's special pattern characteristics. The Moxon also has potential as a fixed satellite antenna when pointed straight upward in a turnstile configuration. The survey closes with an examination of related antenna types that also use multiple forms of coupling between elements.
Moxon Rectangle Notes has over 210 pages of text in 9 well-illustrated chapters. As a bonus, the author has included every model (in EZNEC format) used in his study in a special folder/directory. The collection also contains model-by-equation files in NEC-Win Plus format for designing 50-Ohm and 95-Ohm versions of the rectangle. Also included in the file collection is the AC6LA Windows program for generating Moxon dimensions.
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.
