Inline antenna booster is available in different frequencies. Be sure to match the booster frequency to the frequency being used in your EW-D system.
The EW-D AB inline antenna booster from Sennheiser is designed to improve wireless performance on the EW-D series receiver. It is inserted between a remote antenna and the EW-D ASA antenna splitter (sold separately). Booster compensates for RF signal loss by delivering a 12dB boost. That boost is particularly helpful in situations when long coaxial antenna cables are being run.

Other features include scalable up to 90 channels, an equidistant tuning grid, and compatibility with the Sennheiser Smart Assist app. Built to help your work evolve, the Evolution Wireless Digital series exceeds your needs.
