Avoid painting in the screw holes

Warning: Do not touch the internal components of the antenna when the cover is removed.

Connecting to a Receiver

This antenna is compatible with any receivers, distribution systems, and splitters that operate within the antenna's 

frequency range. For receivers with multiple antenna ports, connect each antenna being used to a separate port.

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. Monitor 

the RF signal from the receiver to ensure optimal signal strength.

RF Gain Set­

ting (dB)

Use Scenario

Pad: 

−10, −20

Provides increased isolation from other RF sources when the desired wireless microphone 

signal strength is strong. If the RF

OVERLOAD LED illuminates when using a higher gain 

setting, the pad should be used to attenuate the signal, but only after verifying that the trans-

mitter is an appropriate distance from the antenna.

0 (Default)

Suitable for typical room installations and provides enough RF gain in most cases when ca-

ble runs are between 10 and 50 feet.

Boost: 

+10

Provides an extra 10 dB of RF gain to compensate for signal loss if using long cable runs (50 

feet or more).

Note: 

Bias power supplied by receiver antenna ports or an external power source is required for antenna to oper-

ate and for illuminating the LEDs.

Selecting Antenna Cables

Use 50 ohm low-loss coaxial cable, such as RG-8U. Shure offers pre-terminated antenna cables ranging from 6 to 

100 feet.

NOTE: 

When ordering cables from Shure, select the low-loss "Z" models (available for longer cables) when using 

frequency bands above 1000 MHz.
