Abstract

529,522. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 26, 1939, No. 15705. Convention date, May 28, 1938. [Class 40 (v)] A short-wave aerial is supported on a conducting mast by elements which serve as phaseinverting means. As shown in plan in Fig. 4, four half-wave radiators are supported from the mast 23 by four quarter-wave sections 7, 9, 19, 21, which are tuned by shorting bars 25, 27, 29, 31. Fig. 5 shows the mast and aerial system in elevation. Since the short-circuited end of each of the quarter-wave sections is a voltage node, it can be grounded without affecting the current distribution over the aerial as a whole. The feed-line is also supported by quarter-wave sections spaced away from the mast as shown at 33, Fig. 5.
