To improve an operator (MC) for a roller blind comprising a motor coupled to a gear rpm-reducer (Mot), a radiofrequency circuit (20), for controlling the motor, which comprises an antenna (22) for transceiving, and power-supply conductors (12) for the motor and the circuit, the operator is equipped with a loop antenna (22) destined to transceive RF signals to/from one of said conductors. Improved noise rejection and better selectivity are obtained. |
