Abstract

PERFECCIONAMIENTOS EN LAS ANTENAS EMISORAS-RECEPTORAS. CONSISTEN EN QUE EL MASTIL DE ANTENA ESTA DIVIDIDO EN UNA PARTE AISLANTE (1A) Y UNA PARTE METALICA (1M). ESTA PRESENTA UNA APERTURA RASGADA (6) POR LA QUE ASOMA EL APENDICE (8) DE UN VASTAGO (9) PORTADOR DE UN CURSOR (10) CORREDERO POR LAS ESPIRAS DE UNA BOBINA (11) DE MODO QUE DESPLAZANDOLO SE VARIA LA RESONANCIA DE LA BOBINA. EXISTE UN CONECTOR (2) DE ACOPLAMIENTO AL APARATO (3), TAL COMO UN <WALKIE-TALKIE>; ENTRE ESE CONECTOR (2) Y LA ALIMENTACION (12) HAY UN SISTEMA ELECTRONICO DE SINTONIA (4) CON UN <LED> (5) QUE CUANDO LA RESONANCIA OTORGADA A LA BOBINA (11) COINCIDE CON LA FRECUNCIA PREESTABLECIDA EN EL APARATO (3) SE ENCIENDE AL MAXIMO. ESTA PREVISTO QUE EL CURSOR SEA FIJO Y LA BOBINA MOVIL LLEVANDO ESTA INCORPORADO UN NUCLEO CORREDERO POR DENTRO DE UN CASQUILLO CONSTITUYENDO UNA CAPACIDAD VARIABLE.
