Active Directional Antenna 470-900 MHz

UA874WB

Overview

Shure UA874 is a directional, active UHF antenna to help improve wireless system reception and signal integrity.

It 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 ½ wave omnidirectional antennas.

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

UA874 can be stand-mounted, suspended from the ceiling, or wall-mounted using the included swivel adapter bracket.
