The Sennheiser AWM UHF I is an active directional antenna for Sennheiser's Evolution Wireless Digital systems (EW-D and EW-DX), covering the UHF I range of 470 to 694 MHz. Installers use it in conference rooms, lecture halls, houses of worship, theatres and broadcast facilities to move the receiving antenna out of the equipment rack and closer to the presenters or performers, which reduces multipath interference and dropouts and improves range where long cable runs are unavoidable. The flat, white square housing is designed to disappear into a room and can be fixed to a wall or ceiling, mounted on a VESA 100 bracket, or screwed onto a standard microphone stand via its 3/8-inch thread. It connects over a 50-ohm BNC cable to a stationary EW-D/EW-DX receiver or the EW-D ASA antenna splitter, which supplies its operating power (12 V DC nominal, 9 to 18 V, maximum 100 mA). It operates from -10 to +55 degrees C. Antenna cables are sold separately.
