Abstract

504,163. Aerials; directive wireless signalling. BERRY,R. J. (Lorenz Akt.-Ges., C.) May 24, 1938, No. 15475. [Class 40 (v)] The "silent zones," formed by the effects of ground radiation in the vertical field from an elevated short-wave transmitter, are filled in, as shown by the shaded parts in Fig. 2, by using a second' transmitting dipole which is arranged at a different elevation to the first. The main aerial 2 is directly energized from the transmitter S, whilst the aerial 3 is energized either by radiation from the first, or through an inductive or other coupling 5. The auxiliary aerial may be replaced by metal sheets, wire-. meshes, or the like. The two dipoles may be provided with reflectors which are alternately keyed to produce a navigational beam..
