Shure UA874WB Active Directional Antenna 470-900MHz
Brand new. Not available for curbside pickup. Online orders only.
The Shure UA874WB is an active directional antenna designed to enhance wireless microphone reception across the 470–900 MHz range. Ideal for demanding wireless setups, this antenna improves signal quality, reduces dropouts, and provides superior RF performance in comparison to standard omnidirectional antennas.
Using a log periodic dipole array (LPDA), the UA874WB delivers a cardioid pattern aimed toward the desired coverage area. This focused design significantly reduces interference and signal reflections from other directions, enhancing system reliability. An integrated low-noise amplifier offers four selectable gain settings to compensate for varying coaxial cable lengths and losses.
Flexible mounting options and rugged construction make the UA874WB suitable for live sound, broadcast, corporate AV, and installed sound environments.
