Abstract

L'invention concerne un procédé pour former un mât d'antenne (2) destiné à un système de télécommunication sans fil. Le mât d'antenne comprend un corps de mât (4) conçu pour former une structure de support destinée à un dispositif d'antenne du système de télécommunication sans fil, le corps de mât comprenant un module inférieur (6) et un module supérieur (8), le module supérieur (8) étant conçu pour comprendre le dispositif d'antenne. Le module inférieur (6) et/ou le module supérieur (8) est/sont conçu(s) pour comprendre un dispositif destiné à être utilisé pour une fonction autre que celle de soutenir le dispositif de support. Le procédé comprend les étapes consistant à: sélectionner un module inférieur (6) et un module supérieur (8) dans un ensemble de modules comprenant au moins deux modules inférieurs différents et/ou au moins deux modules supérieurs différents, et assembler le corps de mât (4) incluant le module inférieur sélectionné (6) et le module supérieur sélectionné (8) pour former un corps de mât assemblé (4). L'invention se réfère aussi à un système de mât d'antenne comprenant un ensemble de modules.
