The rapid development of short-wave communication over long distances over the past decade has brought to life a new field of radio engineering - the technique of directed short-wave antenna devices. High Perspectives . which promised the use of short-wave directional radio transmission, forced individual firms to develop their patented antenna devices at an accelerated pace. "The technique in this case is far ahead of the theory, and along with a large number of practically developed types of directional antennas, we still do not have any complete theory of them and developed a method of technical calculation of their electrical properties. One of the main goals of the author in the preparation of this guide was to fill this gap as far as possible.. [DT This is the first time that we have had to analyze ...... [ ) When developing the theory and methods of calculation, the main attention is paid to horizontal synphase antennas used in our country and in Germany. The same method, without significant changes, can be applied to the study of horizontal directors .. It is much more difficult to calculate vertical and inclined antennas, which require clarification of our knowledge about the influence of soil on radiating systems and further development of the theory. In addition to this main purpose, the compilation of the manual was meant to set out the general principles of the device of directional emitters and to give a number of practical information learned from experience.
