Abstract

895,312. Aerials. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Feb. 21, 1961 [May 25, 1960], No. 18453/60. Addition to 884,889. Drawings to Specification. Class 40(7). An aerial comprises the logarithmic aerial as described in the parent Specification, modified by the addition of a plurality of directors on an axially situated conductor. The conductor extends rearwardly through the active element portion of the aerial and is connected to a reflector, to which reflector the feeder to the active elements is also connected.
