The Shure UABIAST is an in-line adapter that provides 12V DC Bias power to an active antenna or in-line accessory when a receiver's antenna input jack does not provide the necessary power. The UABIAST receives power from a wall outlet using either a Shure PS24 power supply, and passes the RF signal while supplying power to an active antenna or other in-line device. It is capable of supplying power to three in-line amplifiers (Shure UA834), or two in-line amplifiers and one active antenna (Shure UA874).
Note: For cable runs exceeding 25 feet (7.6 meters), an in-line amplifier (Shure UA834) may be required to compensate for signal loss.
Using Shure 50 Ohm BNC-BNC coaxial cables is recommended when making connections.
