Sennheiser ADP UHF Directional Antenna (470-1075 MHz)

The Sennheiser ADP UHF is a passive directional paddle antenna for 470-1075 MHz. Sennheiser specifies a typical gain of 5 dBi, an opening angle of about 100° at -3 dB and a front-to-back ratio above 14 dB. It connects by BNC (50 Ω, no DC path) and has both 3/8-inch and 5/8-inch threads for mic stands. Aimed at the stage, it concentrates reception on the performance area and rejects much of what arrives from behind, such as the audience or the production desk. That makes it the usual step up from rod antennas when receivers sit at front of house or side stage. Use two per diversity receiver or splitter. Its wide range covers both the EW-DX Q1-9 system and the XSW 2 E-band sets, and Sennheiser lists it for EW-D receivers, the EW-D AB booster and the EW-D ASA splitter.
