Abstract

Ce guide d'ondes est caractérisé par le fait qu'il est constitué par un premier tronc creux 10 relié, par une extrémité à l'antenne posée sur le support extensible et rétractable, tandis que son autre extrémité 16, est libre et est repliée perpendiculairement à l'axe longitudinal du tronc correspondant et par un second tronc creux 17, relié par une extrémité, à l'appareillage radio-électrique par l'intermédiare d'un raccord 19, tandis que l'extrémité opposée est libre et repliée perpendiculairement à l'axe longitudinal du tronc correspondant, avec son ouverture tournée vers l'ouverture de l'extrémité libre du premier tronc, ces troncs étant fixés à des tiges de support correspondantes 12 et 20, qui coulissent longitudinalement entre elles. Ce dispositif est applicable notamment aux installations radioélectriques de véhicules.This waveguide is characterized by the fact that it consists of a first hollow trunk 10 connected, by one end to the antenna placed on the extendable and retractable support, while its other end 16 is free and is folded back. perpendicular to the longitudinal axis of the corresponding trunk and by a second hollow trunk 17, connected by one end, to the radio-electric equipment by the intermediary of a connector 19, while the opposite end is free and folded perpendicularly to the longitudinal axis of the corresponding trunk, with its opening facing towards the opening of the free end of the first trunk, these trunks being fixed to corresponding support rods 12 and 20, which slide longitudinally between them. This device is applicable in particular to vehicle radio installations.
