The Sennheiser ADP UHF is a passive directional antenna covering the full 470–1075 MHz UHF range, intended for use with Sennheiser’s Evolution Wireless Digital (EW-D) systems. With its wide bandwidth and directional pattern, it is suited to engineers and AV professionals who need to improve RF reception over distance or reject interference from off-axis sources in live production, broadcast and installed environments.
Compatibility
Designed for the Sennheiser EW-D wireless family and terminated with a 50 Ω BNC (female) connector for connection via coaxial cable. As a passive antenna it carries no DC path, so it cannot pass phantom power to an inline booster — supply any required booster power separately.
