Abstract

24,098. Marconi's Wireless Telegraph Co., and Franklin, C. S. Dec 15. Aerials; directive wireless signalling.-An aerial consists of two rectangular frames A, B, C, D and A, b, c, D arranged in a vertical plane, and a third frame E, F, G, H placed substantially in the same plane as the other two and arranged symmetrically with respect to them. The frames A, B, C, D and A, b, c, D are provided with an oscillation-generator X and a tuning-condenser K ; while the frame E, F, G, H is provided with a condenser L and an oscillation-generator Y of the same frequency as the generator X. In a modification, the frames A, B, C, D and A, b, c, D are connected in series.
