Abstract

Un té de polarisation comprend un premier port (601), un second port (602), un troisième port (603), un condensateur de blocage de courant continu (604), une première inductance (605), une seconde inductance (607) et un modem (606). La seconde inductance (607) est utilisée pour transférer un signal en courant continu entre le premier port (601) et le second port (602). L'invention concerne également un système pour commander une antenne et comprend une unité de commande à distance RCU (902), une antenne commandée par électricité (901), un amplificateur monté sur une tour TMA (903), un té de polarisation (904) et une station de base (905). Selon le té de polarisation fourni par la présente invention, lorsqu'une antenne non commandée par électricité est améliorée en une antenne commandée par électricité, elle n'a aucun besoin d'être remplacée par STMA de façon à diminuer le coût. Il devient inutile d'ajouter un contrôleur d'antenne commandée par électricité, prévenant ainsi le problème technique d'une applicabilité médiocre découlant de l'utilisation d'un contrôleur d'antenne commandée par électricité ; la station de base n'est pas nécessaire pour fournir une interface de connexion, ce qui élimine le besoin d'un câble plus long et diminue la durée du montage.
