Abstract

568,944. Wireless receiving apparatus. ZENITH RADIO CORPORATION. March 18, 1943, No. 20537/44. Convention date, Jan. 16. 1942. Divided out of 568,915. [Class 40 (v)] A radio receiver has a plurality of antenna, at least one of which is stowable within the housing of the receiver and capable of an unstowing movement to bring it to an exposed position outside the housing, such unstowing movement of the antenna operating switch means serving both to connect such antenna to the receiver and to disconnect any other antenna therefrom, while the return of the antenna to stowed position operates the switch means to disconnect the stowed antenna and to connect the other antenna or antennµ.
