DESCRIPTION

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 amplifier is provided by a Shure U4S, U4D, ULXP, ULXS, UR4S
and UR4D Receiver or a Shure UA845 or UA844 Antenna Distribution
System through the connecting coaxial cable.

The UA870 can be mounted on a microphone stand, suspended from the
ceiling, or mounted to a wall using the integrated swivel adapter
bracket. The UA870 is weather resistant for use outdoors. For best
diversity performance, use two UA870 antennas.
