There was also a companion volume not present here which dealt with broad-band antennas, transformers and cables. Fading to blue wrappers, minor soiling. Staplebound. An important engineering work translated and released after the close of World War II. The synopsis describes the importance of radio engineering in wartime, and describes the goal of the document being to bring the best technical information to bear on the war mobilization. Each report was written by different people, presumably experts in their fields. A useful historical document for those studying communications engineering in this period. "Data are presented on numerous types of antennas and their uses. Characteristics of operation and development of fixed antennas, directional-antenna systems with amplifiers, aircraft antennas, and short wave directional antennas are discussed. Each antenna is described and recommendations are made for further development. Raw materials used in manufacture and possible substitutes are listed. Calculations are presented for the design and matching of antennas." (Abstract) Contents include: Report No. 1.
