> **** New book publication - LB Cebik W4RNL (SK) ****
Announcing the release of a new book by LB Cebik, W4RNL
entitled Some Basics of Multi-Band Beam Design.
Includes 52 example working antenna modeling files.
WHAT IS A MULTI-BAND BEAM??
In the words of the author, LB Cebik, a beam is any directional
antenna. In the broadest terms, then, a multi-band beam is any antenna
that is directional on more than one amateur band. (Of course, we can
make multi-band beams for other than amateur radio use, for example,
for the old lower- and higher-frequency television broadcast
channels.) We shall pare down our subject by first limiting ourselves
to horizontal antennas, the type used in the upper HF and the VHF
regions of the spectrum.
UNDER A VEIL OF SILENCE
The process of designing multi-band beams has largely hidden beneath a
veil of silence. Those who pursue this work very often have a
proprietary interest in the designs. Some with a virtually intuitive
knack for the process very often cannot clearly articulate what they
do so well. So most amateur literature simply passes over the subject
or presents a design without much theoretical commentary. We, the
outsiders who look in on multi-band beam design, view it as a mystery,
as a function of secret optimizing software, as esoteric knowledge to
which the average amateur is denied access.
This 247-page volume simply presents what I have managed to learn
about the process over the years. I have certainly not learned
everything-just enough to get started and to realize the limits of
what I know. -LB Cebik
