A thought-provoking book which has been a major contribution to the state of the art from an acknowledged expert. It explains the 'why' as well as the 'how' of HF antennas, and takes a critical look at existing designs in the light of the latest developments. This second edition has been completely revised and greatly expanded. There are more novel antanna designs, including beams which cover more bands with fewer problems, no trap losses and better rejection of interference. A new chapter presents a comprehensive review of ways to make antennas smaller, with particular emphasis on small transmitting loops. An essential reference for the experimenter and enthusiast.
