Biconical television antenna

A newly-developed General Electric Company television receiving antenna, known as a “chicken brooder” antenna, will pick up local programs from mobile units without being aimed at the units. Sixteen times more sensitive than a vertical half-wave antenna usually used for this application, it will be employed by television station WMAL in Washington, D. C. The antenna is constructed with three aluminum sections, each of which is conical in shape, ten feet in diameter, and weighs about 100 pounds. A dipole between the first two sections, which are assembled with the apexes of the cones facing each other, forms the actual receiving antenna to which signals are directed by the coneshaped structure.
