Abstract
476,279. Directive wireless signalling. LORENZ AKT.-GES., C. March 4, 1937, No. 6476. Convention date, March 4, 1936. Addition to 408,323. [Class 40 (v)] In a direction - finding arrangement such as a dipole aerial system C, D coupled to a receiver E, the line coupling the aerial and receiver comprises a cable L of the screened concentric or parallel feeder type which is coiled near the aerial into a choke Dr to inhibit the flow of cophasal currents therein. An iron core Fe may be provided in the coiled portion, and the feeder may be coiled at a plurality of points. other aerial systems may be substituted for that shown, e.g. rotatable or crossed loops, Adcock systems and beacon transmitting systems.
