SHURE UA874WB Active Directional Antenna


The UA874WB delivers improved wireless signal reception with integrated amplification. Features include greater rejection of RF signals outside the coverage area and an integrated amplifier with 4 gain settings.


With the SHURE UA874WB, you’ll experience improved wireless reception. This UHF antenna uses a log periodic dipole array to produce a cardioid pattern towards the desired coverage area, achieving greater rejection of RF signals outside the area than standard ½ wave omnidirectional antennas. An integrated amplifier with four gain settings compensates for varying degrees of coaxial cable signal loss. The UA874 can be stand-mounted, suspended from the ceiling, or wall-mounted using the included swivel adapter bracket.

We offer both dry hire and full production service if required. We aim to provide the best service in the metro Sydney area with our own transport, experienced technicians, and operators. We charge you only for the days the equipment is in use and not for the days it is merely being transported, setup/bumped out. For multiple-day hire, our hire rate is also very competitive.
