    • A UHF antenna for black and white and color television receivers embodies a dished reflector and coacting a dipole mounted a fraction of a wave-length in front of the reflector and being of bow tie configuration. The antenna possesses broad band characteristics for wide angle reception, and wide frequency deviation at UHF wave-lengths. The antenna structure which is for indoor use is fabricated from simple sheet metal components and embodies an integral support base which can be manually adjusted in any direction. Economy and simplicity of construction are featured.
    • 用于黑白和彩色电视接收机的UHF天线体体现了一个碟形反射器,并将偶极子与反射器前面安装了一小部分波长并且具有弓形结构。 天线具有广角接收的宽带特性,UHF波段宽频偏。 用于室内使用的天线结构由简单的钣金部件制成,并且具有可以在任何方向上手动调节的整体支撑基座。 具有经济性和简易性。
