Image: Corner reflector TV antenna

Description: A drawing of a corner reflector UHF television antenna from a 1954 advertisement in an electronics magazine. The corner reflector was a common antenna used for analog UHF TV reception. It consists of a "bow tie" dipole driven element made of a pair of sheet metal triangles suspended between two flat rectangular metal grill reflecting surfaces at an angle of 90°. The corner reflector's advantages were a high gain of 12-15 dBi, a large front-to-back ratio, and a wide bandwidth, much wider than the Yagi antenna. Alterations to image: Cropped out the rest of the advertisement. Cloned in a little of the reflector screen in upper left corner where it was obscured by other picture elements. Added shading to bow-tie dipole to make its shape clearer.
