ARRL ANNOUNCES VOLUME 4 OF POPULAR ANTENNA COMPENDIUM SERIES

Hams just love antennas ... and they love to read about them, and write about
them too! The American Radio Relay League, Inc., is proud to announce
publication, in February 1995, of the fourth volume in the popular ARRL
Antenna Compendium series. There are 38 articles inside, covering a wide
range of antenna related topics. There are simple, practical antenna
projects, and there are heavy-duty, theoretical treatments of complex arrays. 

Since sunspot activity will be low for the next few years, seven articles are
devoted to 80 and 160 meters, including some truly gargantuan arrays. Hams
daydream about their rock-crushing low-band signals, if only they could get
that new 200-foot tower for Christmas. Sigh. 

The book has articles for mobile work too, including one by Leon Braskamp,
AA6GL, analyzing all the compromises involved making a short mobile whip work
on HF. And there are also detailed theoretical treatments on this subject by
Jack Belrose, VE2CV, and Jack Kuecken, KE2QJ. There's a section on portable
or temporary antennas that will start a ham thinking about June Field Day _
especially when it's snowing outside. 

Modeling antennas by computer is all the vogue nowadays, but the novice
modeler should be wary _ there are numerous traps and pitfalls to avoid. This
volume has six articles devoted specifically to modeling, including one by
Brian Beezley, K6STI, documenting an idea that failed miserably _ and most
importantly why it failed. Bob Haviland, W4MB, eloquently describes the
history of the "Method of Moments" modeling technique, and Carl
Luetzelschwab, K9LA, revisits the quad versus Yagi controversy, with detailed
computer models. 

The research behind many of the articles in this volume involved extensive
computer modeling, followed by building and testing real antennas to verify
the models. For the first time in the Antenna Compendium series, a 3.5-inch
diskette is bundled with the book. The disk contains the source data files
and the resulting pattern plot files created by the authors to model their
antennas. Also included is a nifty PLOT program by K6STI to view pattern
plots. With PLOT, you can change from polar to rectangular presentations,
zoom them, overlay other patterns for instant on-screen comparison, and print
out the patterns. 

So, curl up with this book and do some reading. Then warm up your computers
and your soldering irons, and don your safety climbing belt. There's
something of interest here for just about every antenna enthusiast!
