Abstract

L'invention concerne un dispositif pour le traitement des signaux à haute fréquence dans la gamme VHF et UHF qui sont reçus par un réseau d'antenne. Selon l'invention, un noyau 130 a une configuration en boucle fermée; des lignes de transmission 110 et 120 sont enroulées autour de la configuration du noyau 130 dans le même sens et avec un nombre prédéterminé de spires; l'extrémité 141 de la ligne 110 est couplée à la première borne d'antenne, l'extrémité 142 de la ligne 120 est couplée à la seconde borne d'antenne, l'extrémite 143 de la ligne 110 est couplée à l'extrémité 143 de la ligne 120, l'extrémité 151 de la ligne 110 est couplée à la borne d'entrée de répartiteur, l'extrémité 152 de la ligne 120 est couplée à la seconde borne d'entrée de répartiteur, l'extrémité 153 de la ligne 110 est couplée à l'extrémité 153 de la ligne 120. L'invention s'applique notamment aux récepteurs de télévision.
