![]() ![]() Other Software in the 19th Edition of The ARRL Antenna Book Data: HF Propagation Forecasts (Summary only in printed book Summary and Detailed on CDROM version)-144 QTHs around the world.The ARRL Antenna Book FOR RADIO COMMUNICATIONS Pete speculated that the elevation-angle statistics provided with the Antenna Book might be “too inclusive” - because they do cover all portions of the 11-year solar cycle. Software Included with the 19th Edition of The ARRL Antenna Book YT and Elevation Statistics: Pete Smith, N4ZR, wrote an interesting article in Jan/Feb 2001 NCJ, entitled “Scoring Your Antenna System.” He described a metric for ranking stacked Yagis using YT as the computing engine. Software Included with the 19th Edition of The ARRL Antenna Book DOS Software: YT - Yagi Terrain analysis, with elevation-angle statistics for QTHs around the world SCALE for scaling Yagis to other frequencies/tapers AAT - Analyze Antenna Tuner LPDA (by Roger Cox, WB0DGF) MOBILE (by Leon Braskamp, AA6GL) GAMMA Software Included with the 19th Edition of The ARRL Antenna Book Software Included with the 19th Edition of The ARRL Antenna Book Windows Software: TLW - Transmission Line for Windows YW - Yagis for Windows GeoClock (by Joe Ahlgren) Active Beacon Wizard (by Jim Tabor, KU5S) quad and 5-ele.Yagi, 26’ booms - More elements help!Ĭhap 13, Long-wire and Traveling-Wave AntennasĬomparing 5-wavelength Long-Wire to a 4-element Yagi and a dipoleĬomparing 3-wavelength terminated Rhombic to a 4-element Yagi and a dipole You’ll find lots of comparisons of antennas thanks to the latest computer modeling software.Ĭomparing 16.2” wide loops at 14.2 MHz to dipole and ground plane.Ī neat high-voltage “trombone” variable capacitor, made of 3/4” and 1/2” copper pipes and Teflon tape insulation.ĭipole compared to 2-, 3- and 4-element Collinear arraysĬorrecting performance problems with a stubĪdding a stub, retuned elements and a directorĬomparing monoband 3-ele. Major Changes Here are some examples of the kind of changes you’ll find in the paper book. ![]() I received tremendous help from the following contributors: Rudy Severns, N6LF - Chap 8, Multielement Arrays Frank Witt, AI1H - Chap 9, Broadband Antenna Matching LB Cebik, W4RNL - Chap 10, LPDAs Kurt Andress, K7NV - Chap 22, Antenna Supports ![]() The material in the book + augmented software/data is available on CD-ROM also. Major Changes Nine chapters were greatly upgraded or even completely rewritten - About 40% of the book changed materially. ![]() Dean Straw, N6BV Senior Assistant Technical Editor, ARRL What’s New in the 19th Edition of The ARRL Antenna Book?īy R. ![]()
