UA874WB

Improve wireless signal reception for UHF wireless systems with the Shure UA874WB, a wideband active directional antenna with a frequency range extending from 470 to 900 MHz. The antenna uses a log periodic dipole array to produce a cardioid pattern towards the desired coverage area with greater rejection of RF signals outside the coverage area when compared to standard 1/2-wave omnidirectional antennas.

An integrated amplifier with four gain settings compensate for varying degrees of coaxial-cable signal loss.

The UA874WB can be stand-mounted, suspended from the ceiling, or wall-mounted using the integrated swivel adapter bracket.
