arrl antenna book 22nd pdf download
The package of angle-of-arrival files created by Dean Straw, N6BV, in support of HFTA terrain analysis may have been partially installed or omitted entirely. The entire package, including antenna models, is available as a downloadable zip file at the following link:
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.
ARRL antenna modeling files for the ARRL Antenna Book - the set of EZNEC modeling files represent many of the antennas discussed in the Antenna Book. The models are grouped in folders named for the type of antenna they represent. A complete description of the files is included on this README.TXT file which is duplicated on the book's CD-ROM. The models include the new high-performance VHF/UHF Yagi designs by GØKSC created for this edition of the Antenna Book and discussed in Chapter 15. The GØKSC models require EZNEC/PRO4 for accurate reproduction of the radiation pattern, gain, and other specifications.
Broadband wire antenna design for 160 through 40 meters - the following links to downloadable articles and online resources provide additional ideas for broadbanding wire antennas on the MF and lower-HF bands.
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.

EZNEC-ARRL included with the Antenna Book's 22nd edition is a special version of EZNEC 5.0 - its primary purpose is to enable viewing and analysis of the example antennas included with the Antenna Book. It operates as a normal EZNEC demo program except when a specially "signed" EZNEC description file (included on the Antenna Book CD) is opened. When analyzing a "signed" file, EZNEC-ARRL becomes a fully functional just like the standard EZNEC software. "Signed" files can be modified in any way and analyzed with full standard EZNEC program capability. However, EZNEC-ARRL will revert to demo operation when any file saved by EZNEC-ARRL, including a modified "signed" file, is re-opened. Any version of EZNEC-ARRL (including the versions from previous Antenna Books) will function with "signed" files from any Antenna Book edition and all EZNEC model files are compatible with all EZNEC program types. No other "signed" files are available except the ones furnished with the Antenna Book, and EZNEC-ARRL can be obtained only by purchasing the Antenna Book.
