Abstract

L'invention concerne un boîtier d'antenne monobloc à monter dont la plaque du corps de boîtier est enduite de couches principales, de revêtements extérieurs et de revêtements intérieurs, ces derniers étant tous deux reliés. La couche principale adjacente à la plaque est assemblée avec l'autre couche principale. Les revêtements intérieurs sont, à l'instar des revêtements extérieurs, directement reliés. Ladite plaque du corps de boîtier est fixée par l'intermédiaire d'un joint à mortaise. L'invention permet de remédier aux insuffisances électriques et mécaniques du boîtier d'antenne. Par ailleurs, l'assemblage de l'antenne s'en trouve simplifié et l'état de tension de la partie inférieure du boîtier est amélioré.
