Abstract

Una disposición de antena directriz para la gama de ondas decimetricas, en especial para las bandas IV y V de televisión, con al menos una parte primaria y una parte secundaria de antena que consiste en una superficie reflectora realizada predominantemente en construcción abierta y tiene en la gama de ondas de funcionamiento una superficie curvada al menos unidimensionalmente, con preferencia a la manera de un espejo parabólico-cilíndrico, caracterizada porque la superficie del reflector está formada por una superficie (superficie parcial) de un primer soporte y dos superficies parciales dispuestas simétricamente en este soporte y curvadas al menos unidimensionalmente, pudiendo bascular ambas en aproximadamente 90º en dirección a la parte primaria de la antena, ya sea en torno a un eje común o en torno a sendos ejes propios que discurren paralelamente a la dirección longitudinal del primer soporte, envolviendo las dos superficies parciales en estado basculado hacia dentro a toda la parte primaria de la antena con inclusión de la construcción de soporte formada por al menos un segundo soporte, dispuesta delante de la superficie del primer soporte que forma una parte de la superficie del reflector y fijada al primer soporte.
