The Sennheiser EW-D AB 5-S is an active antenna booster designed for use with EW-D (Evolution Wireless Digital) systems. It increases antenna gain to compensate for long cable runs or signal loss in complex RF setups. This helps maintain strong and stable reception, especially in multi-receiver installations, rack systems, or large venues.
