Description

The AB 4-AW+ Antenna Booster from Sennheiser is an upgraded version of the renowned AB 3, tailored to meet the needs of the evolution wireless G4 system. With enhanced functionality and support for wider switching bandwidths, the AB 4 is an indispensable tool for ensuring optimal RF performance in professional wireless setups.

This filtered, inline antenna booster module is equipped with BNC connectors and delivers +10 dB of amplification, effectively compensating for signal loss caused by long antenna cable runs. This makes it a crucial accessory for maintaining strong and stable signal transmission in large venues, outdoor events, and complex audio environments.

Designed with versatility in mind, the AB 4-AW+ is not only fully compatible with Sennheiser’s latest G4 systems—including the ew 300 G4 and ew 500 G4, which offer tuning bandwidths up to 88 MHz—but it also integrates seamlessly with legacy G3 evolution wireless systems. This backward compatibility ensures flexibility and ease of integration for users upgrading their equipment or managing mixed-system environments.

With its robust construction and ability to support high-bandwidth applications, the AB 4-AW+ provides reliable, interference-free signal performance, making it an essential choice for professional audio engineers and performers who demand the best from their wireless systems. Whether you are managing a small installation or a large-scale production, the AB 4-AW+ ensures smooth operation and uncompromising RF clarity.
