This web page is for information that extends or supports the ARRL Antenna Book, 24th edition. The section for each edition contains links to supplemental files and software, non-ARRL documents, and errata and corrections.
Supplemental information is available as a downloadable package beginning with this edition. You will find an access code on a sheet inside the front cover with complete instructions. Once installed, use Adobe Reader to access the PDF files. See the Software folder for HFTA angle-of-arrival files if your installation did not produce a complete, world-wide set of files.
The installation software will create Desktop shortcuts - they will all have the same ARRL-diamond icon and the names will all begin with "ARRL Antenna Book" so it can be hard to tell what each of the shortcuts activates. Holding your cursor over the shortcut will expand the name to the full name. Or you can rename the shortcuts by right-clicking on the shortcut and selecting Rename. One suggestion is to use names like "AntBk Contents", "AntBk Suppl", "AntBk SWare", and so forth.
Some readers report that the version Adobe Reader Touch, provided with Microsoft Apps, does not support all of the PDF features. If this is a problem, download the free Adobe Reader DC from the Adobe website at get.adobe.com/reader which does support the necessary elements, such as bookmarks. Note that the website for downloads will also download a Google Chrome extension and two McAfee security applications unless you opt out by unchecking the necessary boxes.
Printed-circuit boards for many current and previous Antenna Book projects are available from FAR Circuits.
Installing and Running HFTA, TLW, and YWThe programs HFTA, TLW, and YW are known to have difficulty running on 64-bit versions of Windows operating systems. They were developed for and run on 32-bit versions of Windows operating systems. If you experience problems, try the "Run as Administrator" option when starting the program. There are no plans to update the software.
If you are unable to install the software from a CD-ROM, transfer the file to a flash drive and then install it from the flash drive. It may also be possible to copy, not install, the file to the computer's hard drive and then install it from the hard drive but the flash drive approach has been the most reliable option.
SCALE and MAKEVOA
These are MS-DOS programs and will not run under current versions of Windows. The emulator program DOSBox can be used to run old MS-DOS programs on new computers. It is an emulator designed to run old computer gaming software.
The following list includes Windows-based software utilities that support various topics in the Antenna Book. Chapter numbers refer to the primary chapter in the ARRL Antenna Book that references the software. No additional documentation is available beyond what, if any, is provided with the software.
Unless otherwise noted, all of the software listed here can be downloaded to your hard drive, unzipped if necessary, and run directly from the Windows Start menu without requiring installation in the Windows system.
Chapter 1 - Antenna Fundamentals
SCALE.ZIP - a software utility to change the frequency of YW antenna models while compensating for element diameters and taper. Models from other software can be used as described in the documentation included with the utility.
Chapter 4 - Radio Wave Propagation
RngBrg.ZIP - software to compute the range and bearing from a point at one latitude/longitude to another.
Chapter 6 - Multielement Arrays
Arrayfeed1.zip - this is a link to software by W7EL to design feed systems for phased array using transmission lines. There are three files - a readme file, a help file (.chm), and the program itself (.exe). Previous editions contained an incomplete ZIP file that omitted the .exe file. All three elements of the program may be downloaded from the author's website.
SCALE.ZIP - see Chapter 1 above.
ARRL-EZNEC Phased Array files - these files are referenced in the array design section by Roy Lewellan, W7EL and were mistakenly omitted from the download package for the book
Chapter 7 - Log Periodic Antennas
Log Periodic Element and Phase Line Calculator - Spreadsheet to calculate LPDA element lengths and spacings, along with phase line impedance, by Dennis Miller, KM9O. This spreadsheet is in Excel format (XLS) and was last updated on 12 Sep 2011.
Chapter 11 - HF Yagi and Quad Antennas
GAMMAMW4.ZIP - An improved version of the previous utility GAMM2-1 that corrects a calculation problem that fails to find solutions to the calculations when the combination of the desired feed line impedance exceeds the product of the raw antenna resistance and the gamma step-up value. The code was developed by Bill Wortman, N6MW and generously donated to the ARRL and the readers of the Antenna Book, ARRL Handbook, and Low-Band DXing by ON4UN. The ARRL also wishes to thank Greg Ordy, W8WWV for testing the code.
EFFLEN.ZIP - A software routine (written in FORTRAN) to calculate effective lengths of antenna elements.
Chapter 21 - Mobile and Maritime HF Antennas
MOBILE.ZIP - Mobile whip design software by Leon Braskamp, AA6GL. The compressed file includes MOBILE.EXE - the software - plus a desktop icon file.
Chapter 23 - Transmission Lines
Two-Wire Feed Line and Radiated Power Calculator - Spreadsheet to calculate the impedance of parallel-conductor line and the amount of radiated power by Dennis Miller, KM9O This spreadsheet is in Excel format (XLS) and was last updated on 12 Sep 2011.
AAT.zip - software to analyze antenna tuners by Dean Straw, N6BV. The compressed file includes AAT.EXE - the software - plus a PDF instruction file, desktop icon, and associated LOG and SUM file examples. The program will not run under 64-bit operating systems. The program has been run successfully under versions of Windows that have 32-bit/16-bit compatibility, such as XP and Vista. It will not run under 64-bit versions of Win 7/8/10.
The concept of impedance matching is explained by Lou Ernst, WA2GKH in a two-part tutorial "Load to Source Matching". The tutorial consists of a text-and-figures presentation explains the concept and process. The presentation is accompanied by an Excel spreadsheet that allows the student to experiment and observe the effects of matching.
