DC power insertion/extraction system to power any device using the coaxial feed line. Rating: 1.5 A, Frequency range: 1.8 to 54 MHz. Includes DC power insertion unit and DC power extraction unit.
These premium quality, Bias-T Plus and Bias-T MASTER are stand-alone weatherproof units that permit the insertion or extraction of DC control signals of up to 1.5 amps on your coax cable.
By inserting the control voltage on the coax cable feed-line, you eliminate the requirement for external DC wires for powering remote devices.
The Bias-T Plus and Bias-T Master weatherproof assembly can be placed indoors or outdoors for maximum flexibility. Typically, one Bias-T unit will be placed indoors for inserting DC on your coax feed-line, and one Bias-T MASTER will be placed at the remote device where the DC voltage is extracted.
