The ARRL Antenna Book, 21st Edition

Radio amateurs and professional engineers turn to The ARRL Antenna Book as THE source of current antenna theory and a wealth of practical how-to construction projects. Use this book to discover even the most basic antenna designs • wire and loop antennas, verticals, and Yagis • and for advanced antenna theory and applications. Many of the antennas in this edition benefit directly from advances in sophisticated computer modeling. The 21st edition has been extensively revised to include information you can use to build highly optimized or specialized antennas. The book includes new content on Near Vertical Incidence Skywave (NVIS) techniques, phased arrays, S-parameters as used in modern vector network analyzers (VNA), Beverage receiving antennas, mobile "screwdriver" antennas, ionospheric area-coverage maps, and much more. A fully searchable CD-ROM is included, containing The Antenna Book in its entirety. The CD-ROM also contains additional utility programs, including: YW (Yagi for Windows), TLW (Transmission Line for Windows), HFTA (HF Terrain Assessment for Windows), Range-Bearing, Arrayfeed1, and EZNEC-ARRL.
