The UABIAST In-Line Power Supply with PS23US by Shure is for providing 12V DC bias power to an active antenna or in-line device over BNC coaxial cable. It is used when a wireless receiver's antenna input jack does not provide the necessary power or, when used without an antenna distribution amplifier.
The UABIAST receives power from a wall outlet using a Shure PS21 or PS23 power supply and passes the RF signal and power to an active antenna or in-line device. The UABIAST is capable of supplying power to three in-line amplifiers (Shure UA830), or two in-line amplifiers and one active antenna (Shure UA874). A PS23 power supply is included. (The UA830 and UA874 are sold separately.)
