Avantageusement, ledit support porte des moyens de maintien unidirectionnel dudit support sur un élément de carrosserie du véhicule, les directions dans lesquelles les moyens de maintien et les moyens de montage sont opérationnels étant les mêmes mais de sens opposés ; de préférence, les moyens de maintien sont des moyens de clipage élastique logés dans une rainure ménagée à la surface extérieure d'une zone de positionnement dudit support qui se prolonge selon la jupe cylindrique ; la zone de positionnement est placée au droit de l'élément de carrosserie qui présente une ouverture que la zone de positionnement traverse, la zone de positionnement et l'ouverture ayant des sections qui se correspondent, au jeu de montage près ; selon une forme de réalisation préférée, la section de la zone de positionnement et celle de l'ouverture de l'élément de carrosserie sont rectangulaires ; les moyens de maintien s'étendent selon deux côtés parallèles de l'ouverture dans deux rainures parallèles de la zone de positionnement ; la zone de positionnement porte un pion de détrompage s'étendant axialement dans une échancrure de détrompage ménagée sur un bord de l'ouverture de l'élément de carrosserie.Advantageously, said support carries unidirectional holding means of said support on a bodywork element of the vehicle, the directions in which the holding means and the mounting means are operational being the same but in opposite directions; preferably, the holding means are means of elastic clip housed in a groove formed on the outer surface of a positioning zone of said support which extends along the cylindrical skirt; the positioning zone is placed in line with the bodywork element which has an opening through which the positioning zone passes, the positioning zone and the opening having sections which correspond, apart from the assembly clearance; according to a preferred embodiment, the section of the positioning zone and that of the opening of the bodywork element are rectangular; the holding means extend along two parallel sides of the opening in two parallel grooves in the positioning zone; the positioning zone carries a keying pin extending axially in a keying notch formed on an edge of the opening of the bodywork element.

Avantageusement, les moyens de montage sont constitués par une bague à lèvre intérieure disposée axialement entre une portée transversale du support d'écrou et l'écrou prisonnier ; l'élément de carrosserie est métallique et une rondelle de masse métallique à griffes est disposée axialement entre l'élément de carrosserie et le support d'écrou prévu également métallique.Advantageously, the mounting means consist of an inner lip ring arranged axially between a transverse bearing surface of the nut support and the captive nut; the body element is metallic and a metal ground washer with claws is disposed axially between the body element and the nut support also provided in metal.

De préférence, le support d'écrou est muni d'une cheminée centrale et d'une gouttière à section en U disposée transversalement par rapport à la cheminée dans laquelle elle débouche, la cheminée et la gouttière définissant un passage en L pour le câble d'antenne, la cheminée s'étendant dans le support et dans la jupe cylindrique selon leur axe et la gouttière traversant une échancrure longitudinale prévue dans la paroi de la jupe ; un anneau cylindrique radialement élastique est disposé entre le support et la cheminée ; un couvercle ferme la gouttière.Preferably, the nut support is provided with a central chimney and a gutter with U-section arranged transversely with respect to the chimney into which it opens, the chimney and the gutter defining an L-shaped passage for the cable. 'antenna, the chimney extending in the support and in the cylindrical skirt along their axis and the gutter crossing a longitudinal notch provided in the wall of the skirt; a radially elastic cylindrical ring is disposed between the support and the chimney; a cover closes the gutter.

Avantageusement, le support d'écrou est solidaire d'un boîtier destiné à recevoir des moyens électriques associés à l'antenne ; lorsque la cheminée est fermée par un couvercle, de préférence le couvercle ferme également le boîtier.Advantageously, the nut support is integral with a housing intended to receive electrical means associated with the antenna; when the chimney is closed by a cover, preferably the cover also closes the housing.

Les figures représentent une embase destinée au montage d'un brin d'antenne, non représenté, sur un élément de carrosserie 19 d'un véhicule automobile.The figures show a base intended for mounting an antenna strand, not shown, on a bodywork element 19 of a motor vehicle.

En se reportant aux figures 1 à 7, on voit que l'embase est constituée d'une pièce creuse 11 moulée en matière plastique définie par une paroi 2 de forme générale tronconique développée à partir d'une base 3 en forme générale d'ellipse entourée à sa partie inférieure d'une lèvre d'étanchéité 4 en appui sur l'élément de carrosserie 19.Referring to Figures 1 to 7, we see that the base consists of a hollow part 11 molded in plastic material defined by a wall 2 of generally frustoconical shape developed from a base 3 in general shape of ellipse surrounded at its lower part by a sealing lip 4 bearing on the bodywork element 19.

A la partie supérieure de la pièce creuse 11, la paroi 2 est prolongée par un bossage 5 de forme extérieure tronconique maintenant par surmoulage un pion de fixation 9 métallique, par exemple en laiton ; le pion 9 est fileté intérieurement et est destiné à recevoir un embout fileté extérieurement du brin d'antenne non représenté, l'axe 6 du pion 9 et du bossage 5 étant incliné vers l'arrière du véhicule automobile.At the upper part of the hollow part 11, the wall 2 is extended by a boss 5 of frustoconical external shape now by overmolding a metal fixing pin 9, for example made of brass; pin 9 is internally threaded and is intended to receive an externally threaded end of the antenna strand not shown, axis 6 the pin 9 and the boss 5 being inclined towards the rear of the motor vehicle.

La pièce creuse 11 en matière plastique recouvre un support 12 en métal, par exemple en zamac, ayant une face transversale 8 en regard de la face extérieure de l'élément de carrosserie 19 ; le support 12 est prolongé vers le haut jusqu'au voisinage du bossage tronconique 5 en sorte qu'il entoure le pion de fixation 9 sur une grande partie de sa hauteur pour constituer un blindage électrique, une matière isolante 44 isolant électriquement le pion de fixation 9 par rapport au support métallique 12.The hollow piece 11 of plastic material covers a support 12 made of metal, for example of zamak, having a transverse face 8 opposite the external face of the bodywork element 19; the support 12 is extended upwards to the vicinity of the frustoconical boss 5 so that it surrounds the fixing pin 9 over a large part of its height to constitute an electrical shielding, an insulating material 44 electrically insulating the fixing pin 9 relative to the metal support 12.

Le support métallique 12 comporte une jupe cylindrique 13 portant extérieurement un filetage 14 recevant un écrou de serrage 15. L'écrou 15 est porté par un support d'écrou 16 ayant une paroi cylindrique 38, entourant la jupe cylindrique 13 du support métallique 12 et dont l'extrémité supporte l'écrou 15 à la manière d'un écrou prisonnier : pour ce faire, la paroi 38 du support d'écrou 16 est munie à son extrémité d'un rebord circulaire 57 de centrage prolongé selon des pattes 46, par exemple trois pattes 46 disposées à cent quatre-vingt degrés, rabattues dans une gorge circulaire 45 ménagée à la périphérie de l'écrou 15 ; ainsi, l'écrou 15 est solidaire du support d'écrou 16 tout en pouvant tourner par rapport à lui. Comme on le voit sur le dessin, en particulier sur la figure 4, la gorge circulaire 45 est inclinée dans le sens montré sur la figure, c'est-à-dire que le fond de la gorge 45 est plus proche de la face transversale extérieure de l'écrou que ne l'est l'entrée de la gorge : grâce à cette disposition, il suffit d'une poussée de l'écrou 15 vers le support d'écrou 16 pour qu'automatiquement par coopération avec la bordure intérieure inférieure inclinée de la gorge 45 les pattes 46 soient rabattues dans la gorge 45 et maintiennent l'écrou 15 axialement tout en lui permettant de pouvoir tourner par rapport au support d'écrou 16. Il est possible également, bien entendu, de rabattre les pattes 46 dans la gorge 45 classiquement à l'aide d'un outil de rabattement, la gorge 45 n'étant dans ce cas pas nécessairement inclinée.The metal support 12 comprises a cylindrical skirt 13 externally carrying a thread 14 receiving a tightening nut 15. The nut 15 is carried by a nut support 16 having a cylindrical wall 38, surrounding the cylindrical skirt 13 of the metal support 12 and the end of which supports the nut 15 in the manner of a captive nut: to do this, the wall 38 of the nut support 16 is provided at its end with a circular rim 57 for centering extended along lugs 46, for example three legs 46 arranged at one hundred and eighty degrees, folded down in a circular groove 45 formed at the periphery of the nut 15; thus, the nut 15 is integral with the nut support 16 while being able to rotate relative to it. As seen in the drawing, in particular in Figure 4, the circular groove 45 is inclined in the direction shown in the figure, that is to say that the bottom of the groove 45 is closer to the transverse face outer of the nut than is the entry of the groove: thanks to this arrangement, it is enough to push the nut 15 towards the nut support 16 so that automatically by cooperation with the inner edge lower inclined groove 45 the legs 46 are folded into the groove 45 and hold the nut 15 axially while allowing it to be able to rotate relative to the nut support 16. It is also possible, of course, to fold the legs 46 in the groove 45 conventionally using a folding tool, the groove 45 in this case not necessarily being inclined.

Le support d'écrou 16 est muni de moyens de montage 17 constitués d'une bague, par exemple en matière plastique, ayant à sa surface intérieure une lèvre élastique 25 conique dirigée vers l'extrémité inférieure de la paroi 38 du support d'écrou 16 ; la bague 17 est logée à l'intérieur de la paroi cylindrique 38 du support d'écrou 16 et maintenue axialement par coopération, d'un côté, avec une portée transversale 26 définie par un redent 43 radial de la surface intérieure de la paroi 38 et, de l'autre côté, avec la face supérieure d'extrémité de l'écrou 15 ; le diamètre de la surface cylindrique intérieure de la bague 17 est tel que, lorsque la bague 17 est enfilée sur la jupe cylindrique 13 du support 12, seule sa lèvre intérieure 25 interfère avec le filetage extérieur 14 de la jupe 13 ; compte tenu du sens d'inclinaison de ladite lèvre 25, le montage de la bague 17 sur la jupe 13 est unidirectionnel : la bague 17 est déplaçable vers le haut par rapport à la jupe 13 mais est retenue dans le sens contraire par coopération de la lèvre 25 avec le filetage 14 ; l'ensemble support d'écrou 16 - écrou 15 - bague 17 peut donc être monté sur la jupe 13 et y être maintenu alors que l'écrou 15 n'est pas encore vissé sur la jupe 13.The nut support 16 is provided with mounting means 17 consisting of a ring, for example made of plastic, having on its inner surface an elastic conical lip 25 directed towards the lower end of the wall 38 of the nut support 16; the ring 17 is housed inside the cylindrical wall 38 of the nut support 16 and held axially by cooperation, on one side, with a transverse bearing surface 26 defined by a radial recess 43 of the interior surface of the wall 38 and, on the other side, with the upper end face of the nut 15; the diameter of the inner cylindrical surface of the ring 17 is such that, when the ring 17 is threaded on the cylindrical skirt 13 of the support 12, only its inner lip 25 interferes with the external thread 14 of the skirt 13; taking into account the direction of inclination of said lip 25, the mounting of the ring 17 on the skirt 13 is unidirectional: the ring 17 is movable upward relative to the skirt 13 but is retained in the opposite direction by cooperation of the lip 25 with thread 14; the nut support 16 - nut 15 - ring 17 assembly can therefore be mounted on the skirt 13 and be held there while the nut 15 is not yet screwed onto the skirt 13.

Pour le montage de l'embase sur l'élément de carrosserie 19, celui-ci présente une ouverture 22 de forme rectangulaire ayant une échancrure 24 sur l'un de ses côtés ; le support 12 présente une zone de positionnement 21 qui s'étend perpendiculairement à partir de la face d'appui 8 du support 12 et qui se prolonge selon la jupe cylindrique 13 ; la surface extérieure de la zone de positionnement 21 a une section égale, au jeu de montage près, à celle de l'ouverture 22 de l'élément de carrosserie 19, y compris l'échancrure 24 qui reçoit ainsi un pion 23 s'étendant axialement que porte la zone de positionnement 21 : l'échancrure 24 et le pion 23 constituent donc une échancrure et un pion de détrompage permettant d'assurer que lorsque l'embase est montée sur l'élément de carrosserie, l'axe 6 du pion 9 et du bossage 5 est bien incliné vers l'arrière du véhicule.For mounting the base on the bodywork element 19, the latter has an opening 22 of rectangular shape having a notch 24 on one of its sides; the support 12 has a positioning zone 21 which extends perpendicularly from the support face 8 of the support 12 and which extends along the cylindrical skirt 13; the outer surface of the positioning zone 21 has a section equal, apart from the mounting clearance, to that of the opening 22 of the bodywork element 19, including the notch 24 which thus receives a pin 23 extending axially carried by the positioning zone 21: the notch 24 and the pin 23 therefore constitute a notch and a keying pin making it possible to ensure that when the base is mounted on the bodywork element, the axis 6 of the pin 9 and the boss 5 is inclined well towards the rear of the vehicle.

Une rondelle métallique élastique 27 dite de masse est placée sur la surface supérieure du support d'écrou 16 et entoure la zone de positionnement 21 ; elle présente un évidement central 48 de forme également rectangulaire correspondant à la section de la zone de positionnement 21 ; sur deux côtés parallèles de l'évidement 48 sont prévues des échancrures 49 pour le passage du pion de détrompage 23 ; la rondelle 27 présente un axe de symétrie parallèle aux dits deux côtés parallèles où sont prévues les échancrures 49 : cette disposition confère à la rondelle 27 deux positions, à cent quatre vingt degrés l'une de l'autre, selon lesquelles elle peut être montée, ce qui rend le montage plus aisé ; selon ces dits deux côtés parallèles, la rondelle 27 est munie de pattes 47 élastiques, pliées à quatre vingt dix degrés, destinées à être reçues dans des fentes 54 que présente le support d'écrou 16 pour maintien de la rondelle 27 sur ledit support d'écrou 16 ; à sa périphérie, la rondelle 27 porte des griffes 28 inclinées de part et d'autre du plan moyen de la rondelle 27 ; ces griffes 28 sont destinées à assurer un bon contact électrique entre la partie métallique de l'élément de carrosserie 19 et le support d'écrou 16 qui se trouve ainsi relié à la masse.A resilient metal washer 27 called mass is placed on the upper surface of the nut support 16 and surrounds the positioning zone 21; it has a central recess 48 of also rectangular shape corresponding to the section of the positioning zone 21; on two parallel sides of the recess 48 are provided notches 49 for the passage of the coding pin 23; the washer 27 has an axis of symmetry parallel to said two parallel sides where the notches 49 are provided: this arrangement gives to the washer 27 two positions, one hundred and eighty degrees from each other, according to which it can be mounted, which makes assembly easier; according to these said two parallel sides, the washer 27 is provided with elastic tabs 47, bent at ninety degrees, intended to be received in slots 54 presented by the nut support 16 for holding the washer 27 on said support d 'nut 16; at its periphery, the washer 27 carries claws 28 inclined on either side of the mean plane of the washer 27; these claws 28 are intended to ensure good electrical contact between the metal part of the bodywork element 19 and the nut support 16 which is thus connected to ground.

Le support d'écrou 16 est également muni d'une cheminée centrale 29 portée par une gouttière 30 à section en U disposée transversalement par rapport à la cheminée centrale 29 dans laquelle elle débouche ; la cheminée centrale 29 est reçue dans un alésage 7 s'étendant selon l'axe de la jupe cylindrique 13 en débouchant, d'un côté, à l'intérieur de ladite jupe 13 et, de l'autre côté, à l'intérieur du logement du support 12 qui reçoit l'isolant 44 ; une échancrure 31 traversant radialement la paroi de la jupe 13 et celle de la zone de positionnement 21 permet le passage de la gouttière 30 ; un anneau 33 cylindrique élastique radialement est interposé entre la cheminée 29 et l'alésage 7 ; cet anneau 33 permet de participer, par frottement, au maintien du support d'écrou 16 par rapport au support 12, avant serrage de l'écrou 15, aidant ainsi dans cette fonction les moyens de montage 17 en forme de bague.The nut support 16 is also provided with a central chimney 29 carried by a gutter 30 with a U-section arranged transversely with respect to the central chimney 29 into which it opens; the central chimney 29 is received in a bore 7 extending along the axis of the cylindrical skirt 13 by opening, on one side, inside said skirt 13 and, on the other side, inside the housing of the support 12 which receives the insulator 44; a notch 31 radially crossing the wall of the skirt 13 and that of the positioning zone 21 allows the passage of the gutter 30; a radially elastic cylindrical ring 33 is interposed between the chimney 29 and the bore 7; this ring 33 makes it possible to participate, by friction, in maintaining the nut support 16 relative to the support 12, before tightening the nut 15, thus helping in this function the mounting means 17 in the form of a ring.

La cheminée 29 et la gouttière 30 sont destinées au montage coudé d'un câble d'antenne 42 ; en effet, comme on le sait, la plupart des installations d'antenne à bord d'un véhicule nécessitent que le câble d'antenne 42 s'étende, à l'intérieur de la carrosserie du véhicule, le long de l'élément de carrosserie 19 pour rejoindre, directement ou non, l'appareil radio et/ou téléphone dont est équipé le véhicule. Selon l'exemple représenté, le câble d'antenne 42 est relié à un connecteur 242 pour sa liaison au câble d'antenne proprement dit. L' extrémité dénudée du câble d'antenne laisse apparaître l'âme métallique 53 du câble 42 qui est reliée électriquement, par soudage ou sertissage, à une douille 51 métallique adaptée à recevoir une broche 50, également métallique, solidaire du pion de fixation 9, à sa partie inférieure ; des moyens d'isolation 36 sont prévus entre la broche 50, la douille 51 et le câble 42, d'une part, et la cheminée 29, d'autre part ; de même, d'autres moyens d'isolation 37 sont prévus entre le câble 42 et la gouttière 30 ; les moyens d'isolation 36-37 peuvent être deux éléments cylindriques dont l'un a pour axe l'axe de la cheminée 29 et dont l'autre a un axe perpendiculaire au précédent ; ils peuvent aussi être réalisés sous forme de deux demi-coquilles en forme de L et à section semi-circulaire, raccordées selon un plan de joint correspondant au plan formé par les deux axes ci-dessus, c'est-à-dire parallèle au plan de la figure 6.The chimney 29 and the gutter 30 are intended for the angled mounting of an antenna cable 42; indeed, as is known, most antenna installations on board a vehicle require that the antenna cable 42 extend, inside the vehicle body, along the element of body 19 to join, directly or indirectly, the radio device and / or telephone with which the vehicle is equipped. According to the example shown, the antenna cable 42 is connected to a connector 242 for its connection to the antenna cable itself. The stripped end of the antenna cable reveals the metallic core 53 of the cable 42 which is electrically connected, by welding or crimping, to a metallic socket 51 adapted to receive a pin. 50, also metallic, integral with the fixing pin 9, at its lower part; insulation means 36 are provided between the spindle 50, the socket 51 and the cable 42, on the one hand, and the chimney 29, on the other hand; similarly, other insulation means 37 are provided between the cable 42 and the gutter 30; the insulation means 36-37 may be two cylindrical elements, one of which has the axis of the chimney 29 and the other of which has an axis perpendicular to the previous one; they can also be produced in the form of two L-shaped half-shells with a semicircular section, connected according to a joint plane corresponding to the plane formed by the two above axes, that is to say parallel to the plan of figure 6.

Pour monter l'embase sur l'élément de carrosserie 19, on commence par présenter, par l'extérieur, l'ensemble pièce creuse 11 et support 12 et on engage la jupe cylindrique 13 puis la zone de positionnement 21 dans l'ouverture 22 de l'élément 19, l'ensemble étant positionné par le pion de détrompage 63 qui prend place dans l'échancrure 24.To mount the base on the bodywork element 19, we begin by presenting, from the outside, the hollow part 11 and support 12 assembly and engaging the cylindrical skirt 13 then the positioning zone 21 in the opening 22 of element 19, the assembly being positioned by the coding pin 63 which takes place in the notch 24.

La suite du montage à effectuer de l'intérieur de la carrosserie est facilitée si l'ensemble précédent, pièce creuse 11 et support 12, est maintenu un tant soit peu par rapport à l'élement de carrosserie 19 ; pour ce faire, des moyens de maintien unidirectionnel 18 sont prévus ; ils sont constitués de moyens de clipage élastique réalisés sous forme de barrettes à lèvres 55 logées dans des rainures 20 de section de forme trapézoïdale s'étendant de part et d'autre de la zone de positionnement 21 parallèlement au côté de l'ouverture 22 qui porte l'échancrure 24 de détrompage ; du côté de cette échancrure, la rainure 20 traverse le pion 23 de détrompage ; les lèvres élastiques 55 des moyens de maintien 18 prennent appui sur la face intérieure de l'élément de carrosserie 19 pour retenir axialement le support 12.The remainder of the mounting to be carried out from inside the bodywork is facilitated if the previous assembly, hollow part 11 and support 12, is held as little as possible relative to the bodywork element 19; to do this, one-way holding means 18 are provided; they consist of elastic clipping means produced in the form of lip bars 55 housed in grooves 20 of trapezoidal section extending on either side of the positioning zone 21 parallel to the side of the opening 22 which bears the keying notch 24; on the side of this notch, the groove 20 passes through the coding pin 23; the elastic lips 55 of the holding means 18 bear on the inner face of the bodywork element 19 to axially retain the support 12.

Pour terminer le montage de l'embase, on a d'abord préparé un sous-ensemble constitué du support d'écrou 16, de la rondelle de masse 27, de la bague 17. Le support d'écrou 16 est alors équipé de l'anneau radialement élastique 33 autour de sa cheminée 29, ainsi que du câble 42 avec sa douille 51 et des moyens d'isolation 36, 37, le câble 42 préalablement emmanché dans la cheminée 29 étant ensuite rabattu dans la gouttière 30 qui est ensuite fermée par le couvercle 32 qui comporte une partie 56 correspondante s'étendant transversalement dans l'échancrure 31 et ferme également la partie inférieure de la cheminée 29 ; le couvercle 32 est fixé au support d'écrou 16 par exemple par des vis, rivets ou pions de sertissage en 52, figure 5 ; l'écrou 15 est alors assujetti au support d'écrou 16 par rabattement des pattes 46 dans la gorge 45 de l'écrou.To complete the mounting of the base, we first prepared a sub-assembly consisting of the nut support 16, the ground washer 27, the ring 17. The nut support 16 is then equipped with the radially elastic ring 33 around its chimney 29, as well as the cable 42 with its socket 51 and insulation means 36, 37, the cable 42 previously fitted into the chimney 29 then being folded back into the gutter 30 which is then closed speak cover 32 which has a corresponding part 56 extending transversely in the notch 31 and also closes the lower part of the chimney 29; the cover 32 is fixed to the nut support 16, for example by screws, rivets or crimping pins at 52, FIG. 5; the nut 15 is then secured to the nut support 16 by folding the tabs 46 into the groove 45 of the nut.

Ce sous-ensemble est ensuite monté par dessous l'élément de carrosserie 19 sur le support 12, la cheminée 29 et son anneau élastique 33 prenant place dans l'alésage 7, et les moyens de montage 17 autour de la jupe cylindrique 13 en coopérant de façon unidirectionnelle avec le filetage 14. Il est alors très aisé de visser l'écrou 15, au moyen par exemple d'une visseuse pneumatique.This sub-assembly is then mounted from below the body element 19 on the support 12, the chimney 29 and its elastic ring 33 taking place in the bore 7, and the mounting means 17 around the cylindrical skirt 13 by cooperating unidirectionally with the thread 14. It is then very easy to screw the nut 15, for example by means of a pneumatic screwdriver.

Le support d'écrou 16 peut se prolonger parallèlement à l'élément de carrosserie 19 sous forme d'un boîtier 34, comme le montrent les figures 1 à 3 ; ainsi, cet ensemble 10 peut comporter une alimentation électrique grâce à un câble d'alimentation 40, à connecteur ou non, des moyens électriques 35, pour utilisation de l'antenne pour le fonctionnement à la fois d'un poste de radio et d'un radiotéléphone : le câble 42 est par exemple destiné au fonctionnement du radiotéléphone à l'antenne duquel il est raccordé via le connecteur 242 et un autre câble via un connecteur 41 permet le fonctionnement du poste de radio, les moyens électriques 35 comportant un duplexeur ; le support d'écrou 16 peut être de forme simple et n'être utilisé que pour le montage d'une antenne destinée au seul fonctionnement d'un poste de radio, comme le montre schématiquement les figures 8 et 9 décrites succintement ci-dessous; il est possible également d'incorporer dans ledit support d'écrou 16 des moyens d'amplification pour cette antenne radio alimentés en énergie électrique par un câble d'alimentation 40, comme le montre le schéma de la figure 10 ; ainsi, comme on le voit, une même pièce creuse 11 comportant un même support 12 et un même pion 9 peut être associée à différents supports d'écrou 16 pour le fonctionnement d'une antenne pour un poste radio, avec ou sans amplification, ou pour un poste radio et un radio téléphone, voir pour un radio téléphone seul ; bien entendu, il est possible également, quelle que soit la configuration désirée, de prévoir le même support d'embase tel que décrit en référence aux figures 1 à 7 en n'utilisant que la (ou les) sortie(s) correspondante(s) : on peut ainsi configurer une installation ayant un poste de radio seul, un poste de radio à amplificateur ou bien un poste de radio et un radio téléphone avec une seule antenne grâce à un duplexeur ; pour éviter des erreurs de montage, les connecteurs 41 et 242 peuvent être de couleurs différentes, ou bien l'un peut être un connecteur mâle tandis que l'autre est un connecteur femelle. Comme on le voit sur les figures 1 et 2, le câble d'alimentation 40 et le connecteur 41 sont placés d'un côté par rapport à l'ensemble 10, tandis que le connecteur 242 est placé du côté opposé ; en variante non représentée, le câble d'alimentation 40 et les connecteurs 41 et 242 sont tous trois placés d'un même côté par rapport à l'ensemble 10.The nut support 16 can extend parallel to the bodywork element 19 in the form of a housing 34, as shown in Figures 1 to 3; thus, this assembly 10 may include an electrical supply by means of a supply cable 40, with or without connector, electrical means 35, for using the antenna for the operation of both a radio and a radio. a radiotelephone: the cable 42 is for example intended for the operation of the radiotelephone to the antenna of which it is connected via the connector 242 and another cable via a connector 41 allows the operation of the radio station, the electrical means 35 comprising a duplexer; the nut support 16 can be simple in shape and only be used for mounting an antenna intended for the sole operation of a radio, as shown schematically in Figures 8 and 9 described briefly below; it is also possible to incorporate into said nut support 16 amplification means for this radio antenna supplied with electrical energy by a power cable 40, as shown in the diagram in FIG. 10; thus, as can be seen, the same hollow part 11 comprising the same support 12 and the same pin 9 can be associated with different nut supports 16 for the operation of an antenna for a radio set, with or without amplification, or for a radio and a radio telephone, see for a radio telephone only; of course, it is also possible, whatever the desired configuration, to provide the same base support as described with reference to Figures 1 to 7 using only the (or the corresponding output (s): it is thus possible to configure an installation having a radio station alone, a radio station with an amplifier or else a radio station and a radio telephone with a single antenna thanks to a duplexer; to avoid assembly errors, connectors 41 and 242 can be of different colors, or one can be a male connector while the other is a female connector. As seen in Figures 1 and 2, the power cable 40 and the connector 41 are placed on one side relative to the assembly 10, while the connector 242 is placed on the opposite side; in a variant not shown, the power cable 40 and the connectors 41 and 242 are all three placed on the same side with respect to the assembly 10.

Les figures 8 et 9 représentent la variante évoquée ci-dessus, où seul l'ensemble de fixation de l'embase est représenté ; les éléments analogues à ceux décrits à propos de la variante selon les figures 1 à 7 portent la même référence augmentée de 100 et ne seront donc pas décrits davantage ; la variante des figures 8 et 9 étant spécifique pour le montage d'une antenne destinée au seul fonctionnement d'un poste de radio, le support d'écrou 116 est plus simple que le support d'écrou 16 décrit ci-dessus ; notons que le support d'écrou 116 porte un connecteur 160 pour raccordement du câble 142 au câble d'antenne proprement dit de liaison au poste radio.Figures 8 and 9 show the variant mentioned above, where only the mounting assembly of the base is shown; elements similar to those described in connection with the variant according to FIGS. 1 to 7 bear the same reference increased by 100 and will therefore not be described further; the variant of FIGS. 8 and 9 being specific for mounting an antenna intended for the sole operation of a radio, the nut support 116 is simpler than the nut support 16 described above; note that the nut support 116 carries a connector 160 for connection of the cable 142 to the actual antenna cable for connection to the radio station.
