Abstract

402,834. Directive wireless signalling. FEDERAL TELEGRAPH CO., 200, Mount Pleasant Avenue, Newark, New Jersey, U.S.A.-(Assignees of Kruesi, G. G. ; 230, East 51st Street, New York, U.S.A.) June 11, 1932,No.16570. Convention date, July 29, 1931. [Class 40 (v).] A directional antenna system comprises a paraboloidal reflector constructed of wire mesh and suspended from an array of masts by a system of supporting wires and cables. The pairs of masts 1 and 5, 2 and 6, 3 and 7, 4 and 8, Figs. 1, 2, support main suspension cables 9....12 respectively having attached thereto circumferential cables 13....16 respectively each lying in the plane of the masts from which it is supported. The circumferential cables are intersected by longitudinal cables extending from a supporting ring 17 near the apex of the reflector and guyed by cables 18 anchored at a point 19 to the rear of the reflector. The small apical portion lying within the ring 17 may be of copper &c. sheeting. The conducting mesh 20 constituting the reflecting surface is attached to the system of circumferential and longitudinal cables previously described. The axis of the reflector is arranged at the most suitable angle with the ground for the wavelength used e.g. at 23‹ for a wavelength of 17 metres, and the upper portion of the reflector may be extended to give a vertical opening as shown. Several half-wave. length radiating conductors 26....29, Fig. 5, e.g. designed to transmit waves of 10, 14, 17 and 23 metres respectively may be arranged within the reflector and positioned one quarter wave-length from the apex thereof the 17 metre conductor passing through the focus F. The radiators are preferably arranged to extend approximately parallel with the portion of the reflecting surface closest thereto.
