Abstract

535,707. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct 14, 1939, No. 27932. Convention date, Oct. 15, 1938. [Class 40 (v)] A short-wave aerial for radiating vertically-polarized waves of uniform field-strength in an horizontal plane consists of a series 1 ... 4 of overlapping tapered half-wave tubes arranged co-axially about a common vertical axis 5 and energized in parallel from a feed-line TL. The comparatively-large diameter of the tubes gives the aerial a broad frequency-response. Each dipole is conductively connected at 6 to the supporting mast 5. The whole series is held in alignment by metallic rings 10 which are spaced so as to give maximum impedance between the upper and lower ends of each radiator, and also between the lower end of each radiator and the supporting mast. The transmission line is split into two main branches 11, 12 which are again sub-divided at 13 ... 16. The outer sheath of each branch-line is connected to the mast 5, whilst the centre conductor is attached at 18 to each of the radiators. The dipoles may be aligned in an horizontal instead of a vertical plane.
