The Sennheiser AWM UHF (article 508865) is an active directional antenna for Evolution Wireless Digital systems, covering the UHF I band from 470 to 694 MHz. It is built for installed and portable applications where directional pickup and adjustable gain improve RF reliability, boardrooms, lecture theatres, houses of worship and stage productions running EW-D or EW-DX.
CompatibilityConnects to any stationary Evolution Wireless Digital receiver or to the EW-D ASA antenna splitter. The antenna draws power down the coax via its DC-coupled BNC when used with the EW-D ASA or EW-DX EM 4 (Dante). When used with the EW-DX EM 2 (Dante) or EW-D EM, an optional external power supply is required.
