Bias T Coaxial Power Inserter

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.
