Shure UABIAST In-Line Power Supply with PS23US

The Shure UABIAST-US is an in-line power supply designed to provide 12V DC bias power to active antennas or in-line RF devices through a BNC coaxial cable. This product is essential when your wireless receiver does not have built-in power at its antenna input or when you do not have an antenna distribution amplifier available. It ensures your wireless system components receive the necessary power to operate efficiently without compromising signal quality.

This unit connects easily to a standard power outlet using the included Shure PS23US power supply. It can support up to three connected devices, such as Shure UA830 in-line amplifiers or a combination of one UA874 active antenna with two amplifiers. The UABIAST-US maintains the integrity of the RF signal path with less than 1 dB insertion loss, which means it won’t degrade your signal while powering your equipment.

Ideal for fixed installations where expanding wireless system configurations is necessary, this power supply helps maintain reliable performance in professional audio setups. Whether you are setting up a stage, conference room, or broadcast environment, the UABIAST-US provides a straightforward solution to power multiple RF components through a single unit.
