Abstract
Système d'alimentation périscopique permettant d'utiliser simultanément et séparement deux gammes de fréquence sur une même antenne. Le système comporte un périscope 60 à quatre miroirs, mobile autour de l'axe azimut, un dispositif séparateur 30 des deux gammes de fréquence, et deux dispositifs d'excitation des gammes de fréquence basse et haute 40-50, qui conservent chacun une position fixe quels que soient les mouvements du. périscope autour de l'axe azimut.
