Sennheiser EW-D AB (Q).
TheSennheiser EW-D AB Inline Antenna Boosteris a high-quality, frequency-selective antenna booster that gets inserted between a remote antenna and an EW-D ASA antenna splitter. It delivers a 12 dB boost to compensate for RF signal loss when running long coaxial antenna cables, helping to significantly improve the wireless performance of your EW-D series receiver.
The frequency selectivity of the EW-D AB ensures that all RF signals within the specified R: 520 to 608 MHz frequency range are amplified while RF signals with frequencies outside of the specified range are attenuated.
The EW-D AB receives DC power from the EW-D ASA antenna splitter. A DC pass-through capability enables you to connect up to two EW-D AB per antenna cable line (DC-coupled). A green LED indicates that the unit is receiving sufficient DC power.
