Cubical Quad Notes Volume 3: Multi-Band Quad Questions
By L.B. Cebik, W4RNL

Volume 3 of Cubical Quad Notes extends the work  begun in the first two
volumes. This 3rd Volume in the series explores a  number of questions
involved in the design of multi-band quad beams.  Beginning with
2-element designs, Cebik analyzes element interaction in  spider
designs and then sorts those interactions from others that involve  the
use of a common feedpoint. The work involves the accumulation  of
significant quantities of data in order to develop reliable trends  in
quad performance.

In Volume 1, Cebik reviewed extensively the  design of cubical quad
beams up to the time of its writing.  Designs  consisted of roughly 3
types: full size monoband 2-element quads, shrunken  quads, and
examples of monoband and multi-band quads with more than 2  elements.

Volume 2 endeavored to re-think the quad beam, with special  emphasis
on monoband designs.  To rectify performance deficiencies, the  volume
optimized the performance of monoband beams and committed  the
optimization to a series of computer design programs.

Volume 3 of  Cubical Quad Notes has 249 pages, with 140 illustrations
and numerous data  tables.
