Abstract [English] A radio frequency (RF) antenna tuner block (1000) for individually tuning RF antennas (1010) comprises a plurality of selectively switchable tuning elements (1020) The tuner block further comprises an RF common mode choke (1030) providing an interface between the tuner block (1000) and the RF antennas (1010), and the RF common mode choke (103) is configured to reduce stray currents in the tuning elements of the tuner block. The RF common mode choke comprises two conductors (1032) wound around a common core (1034). The RF common mode choke is positioned between the RF antennas (1010) and input terminals (1022) of the tuner block. [French] Un bloc tuner d'antenne radiofréquence (RF) (1000) pour accorder individuellement des antennes RF (1010) comprend une pluralité d'éléments d'accord sélectivement commutables (1020). Le bloc tuner comprend en outre une self de mode commun RF (1030) fournissant une interface entre le bloc tuner (1000) et les antennes RF (1010), et la self de mode commun RF (103) est configurée pour réduire les courants vagabonds dans les éléments d'accord du bloc tuner. La bobine d'arrêt en mode commun RF comprend deux conducteurs (1032) enroulés autour d'un noyau commun (1034). La self de mode commun RF est placée entre les antennes RF (1010) et les bornes d'entrée (1022) du bloc tuner.
