Sennheiser AC 41 active antenna combiner

The Sennheiser AC 41 Antenna Combiner is a passive device designed to improve the handling of RF signals in professional wireless systems. This combinator allows two signals from separate antennas to be combined into a single output, thus facilitating reception by multiple transmitters without the need to multiply cables or ports on receivers. It is particularly suitable for live, broadcast and fixed installations where high signal quality and efficient configuration are required.

The AC 41 covers a frequency range from 470 MHz to 865 MHz, making it compatible with many Sennheiser wireless systems such as the EW G3, EW G4 and SpeechLine Digital Wireless series. Due to its low insertion loss, less than 1 dB, the combiner maintains the integrity of the RF signal, minimizing attenuation and interference. This is essential to ensure clear and stable audio transmission, especially in environments with multiple signal sources.

The robust and compact design, with high quality BNC connectors, facilitates installation and maintenance in professional environments. In addition, the passive design of the combiner does not require external power supply, making it even easier to use. In summary, the Sennheiser AC 41 is an essential accessory to optimize RF reception and improve the performance of wireless systems in the professional field.
