UA864 -- Wall-Mounted Active Directional
Antenna
General Description
The UA864 antenna provides active directional RF coverage in an easy-to-install, low-profile enclosure that can be
mounted on walls, ceilings, or metal surfaces with improved reception. The paintable, neutral white housing allows
the antenna to blend into corporate or classroom settings. The 4-position selectable gain switch provides attenua-
tion and boost settings to match the antenna to the environment. UHF variants provide wideband RF coverage.
Features
• Low-profile design
• Wall or ceiling mounting options
• Wideband performance (UHF models only)
• Four-position gain switch
• Metal surface mounting capability
• LED indicators for gain settings
• Neutral white, paintable housing
Positioning Antennas for Diversity Reception
The UA864 is a polarized antenna and must be oriented correctly to optimize reception for each transmitter type.
The gain switch indicates the antenna's orientation. Position the antennas using the following guidelines:
Note: The antenna's inner construction may differ for each model variation.

    Note: The antenna requires bias voltage from the receiver or distribution system to operate and for LED function- ality. If these devices do not supply bias voltage, the Shure UABIAST inline power supply can be used. Setting the Gain Switch Use the gain switch to optimize antenna performance for the RF characteristics of the room or location.
