Lectrosonics BIAST DC Power Inserter for UFM230 Filter and Amplifier

Lectrosonics' 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. 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 CH20.

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.
