Abstract

986,836. Aerials. ANTON KATHREIN, [trading as ANTON KATHREIN ALTESTE SPEZIALFABRIK FUR ANTENNEN UND BLITZSCHUTZAPPARATE]. Sept. 19, 1962 [Sept. 20, 1961], No. 35643/62. Heading H4A. In a dipole aerial comprising two primary elements 1 and 1<SP>1</SP> fed by a coaxial cable 3, one element has formed at one end an open-circuited cavity 8 containing a coiled portion of the feeder so that at the frequency of operation the coil and cavity form a parallel resonant circuit to decouple the aerial from the supporting mast 2. In a second embodiment, Fig. 3 (not shown), one primary element is formed by the outer conductor of the feeder and in another embodiment, Fig. 4 (not shown), a synthetic plastic housing encloses the feed point and cavity whilst supporting the upper primary element.
