Braun G. Planning and Engineering of Shortwave Links

Berlin, München: Siemens Aktiengesellschaft, London: Heyden, 1982. — 329 p.If you are a telecommunications engineer or a user or operator of shortwave links, then this book is a valuable account of the design, propagation and mathematical calculation of the parameters of shortwave links in the 1.5 to 30 MHz frequency band. The treatment is detailed and the emphasis on applications and practice.
The introductory chapter on the ionosphere — the transmission medium — leads the reader into the subsequent data on the technical conditions requird for successful shortwave links and the emission of high-quality, reliable signals. Calculation of shortwave paths for both spacewave links over varying distances and groundwave transmission over differing types of ground is demonstrated with the aid of diagrams and examples. The final chapter compares the most widely used antennae for shortwave emitter and groundwave stations, and includes radiation diagrams of distance ranges. Throughout, the most importantdata are summarised in tables.
For engineers in telecommunications departments of public institutions such as the armed services, customs, or the police force, companies operating shortwave stations, engineers dealing with the planning and propagation of shortwave radio, sales engineers required to advise customers, and students and teachers of electrical engineering, Planning and Engineering of Shortwave Links will prove a useful reference manual and study book.
