Shure UABIAST — In-Line Bias Power Adapter
UABIAST Overview
The Shure UABIAST is an in-line power adapter designed to deliver 12V DC bias power over coaxial cable, eliminating the need for separate power runs to active antenna devices. Supporting up to 3 active antenna devices, it simplifies antenna distribution infrastructure in professional wireless installations. It is well suited for audio engineers, system integrators, houses of worship, and touring companies who rely on active antenna systems for reliable RF performance.
By injecting bias power directly through the coaxial signal path, the UABIAST reduces cable clutter and streamlines deployment in both permanent installations and touring rigs.
