Amazon.com description: Product Description: This edition contains BASIC computer programs for antenna design and impedance matching, expanded coverage of long-wire directional antennas and radio-wave propagation theory, and new material on small loop direction-finding antennas. It presents practical projects, providing nuts-and-bolts information on an array of antenna types, including: high frequency dipole, vertically polarized HF, multi-band and tunable wire, hidden and limited-space, directional-phased vertical and directional beam, VHF/UHF transmitting and receiving antennas, antennas for shortwave reception, microwave antennas and mobile, marine and emergency antennas. Also explained are circuits and methods for matching antenna load impedance to an RF source or transmission line, antenna measurement and adjustment methods, antenna measurement and adjustment methods, antenna grounding techniques and how to use the Smith chart as a problem-solving device.
