Shure UA870USTV UHF Active Directional Antenna
for U4S, U4D, ULXP, ULXS, UR4S and UR4D Receivers or UA844 or UA845
Antenna Distribution Systems.
The Shure UA870USTV 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 UA870USTV 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 UA870USTV can be mounted on a microphone stand, suspended
from the ceiling, or mounted to a wall using the integrated swivel
adapter bracket. The UA870USTV is weather resistant for use
outdoors. For best diversity performance, use two UA870USTV
antennas.
