Abstract
ANTENA PERFECCIONADA PARA RADIO DE VEHÍCULOS caracterizada esencialmente por el hecho de estar constituido por un cuerpo filiforme, que adopta perifericamente la forma de un polígono, en un punto de cuya periferia está dotado de una extensión, sobresaliente del polígono, que constituye un núcleo de anclaje sobre una cabeza poliédrica que presenta un orificio central para acople del núcleo y medios de retención eventual con cierre a llave, permitiendo el giro del cuerpo filiforme para orientación.
