Abstract
171,983. Ges. fur Drahtlose Telegraphie. Nov. 24, 1920, [Convention date]. Aerials; atmospherics, eliminating.-In order to eliminate atmospherics, the damping of an aperiodic aerial of the frame type is made so great that the shock-excitation of the tuned receiving circuits is negligible. The consequent weakening of received signals is counteracted by the use of amplifying-valves in cascade which operate at different frequencies.
