Product Details

Overview

The BIAS T is used to apply DC power to a coaxial antenna line for remotely powering the UFM230 filter/amp. The DC power applied to the BIAS T (9 to 16 VDC) appears on the input port of the BIAS T to power the UFM230 through the coaxial cable, but is isolated from the output port so it will not be applied to the input of the receiver.The BIAS T is normally placed near the receiver being fed by the coaxial cable, where power is available. The UFM230 filter/amp and antenna are placed at the opposite end of the coaxial cable, close to the antenna.The Bias “T” is used to insert DC power into a coaxial cable to power a Lectrosonics remote antenna amplifier or filter/amplifier. It is positioned at the receiving end of the coaxial cable to pass DC power from an external source to the coaxial cable running to the antenna. 

An internal blocking diode prevents damage to the Bias “T” if reverse voltage is applied. A self resetting polyfuse protects the unit from damage in the event of a short on the antenna side. Like other Lectrosonics products with a polyfuse, removing the power from the unit for a few seconds will reset the fuse.The Bias “T” consists of a feed inductor to deliver DC to the BNC connector on the antenna side and a blocking capacitor to keep DC from passing through to the receiver. The RF is connected directly from one BNC to the other with only the blocking cap in series. A locking power jack provides the connection to an external power supply such as the Lectrosonics external DC power supply; 9 to 16 VDC; 150 mA or greater capacity.
