TECHNICAL SPECIFICATION
The Shure UA870 is an active UHF wireless directional antenna. It features a log?periodic dipole array. When compared to an omnidirectional 1/2-wave antenna, the?cardioid pattern provided by the UA870 offers enhanced reception of the desired?coverage area and greater rejection of RF signals outside the coverage area.
To compensate for coaxial cable signal loss, the UA870 has an on-board amplifier?that offers user selectable 3 or 10 dB gain. The gain setting is indicated by two?LEDs. Remote 12 Vdc power for the antenna amplifi er is provided by a Shure UR4 or?ULX Receiver or a Shure UA845 or UA844 Antenna Distribution System through the?connecting?coaxial?cable.
