Si l'augmentation de la puissance de sortie d'un brouilleur peut am\u00e9liorer ses capacit\u00e9s de blocage simple, il convient d'\u00e9viter tout effet non d\u00e9sir\u00e9 sur les communications externes. De fortes fuites de signaux provenant de la zone de brouillage peuvent avoir un impact significatif sur les connexions externes. Par cons\u00e9quent, la conception du blindage doit prendre en compte et utiliser des contr\u00f4les techniques pour garantir un blocage pr\u00e9cis et efficace sans cons\u00e9quences impr\u00e9vues.
