WiNRADiO WR-BT-3500 VHF/UHF Power Injector (Bias 'T')

WR-BT-3500 VHF/UHF Power Injector (Bias 'T') This device provides a means to inject DC power in a coaxial cable, to power remotely-located devices such as active antennas, low-noise amplifiers and downconverters. It features a very flat frequency response, making it possible to use this device in a very wide frequency range, from 30 to 3500 MHz.

The WiNRADiO WR-BT-3500 Power Injector is especially suitable for use with WiNRADiO WR-DNC-3500 Frequency Downconverter or the WR-LNA-3500 Low Noise Amplifier.

WiNRADiO WR-BT-3500 Power Injector Features

 Frequency range 50 to 3500 MHz
 Flat frequency response
 Low insertion loss
 Wide range of DC voltages
 Rugged weatherproof construction
 Simple installation


WR-DNC-3500 Downconverter Installation

In this example, the WR-DNC-3500 downconverter is placed close to the antenna and powered via the coaxial cable. On the receiver side, the power is injected in the coaxial cable using the WiNRADiO WR-BT-3500 Bias 'T' device. Such arrangement makes it possible to minimize losses in the cable if the antenna is located at a greater distance from the receiver.

A suitable 12 V power supply to use with the WR-BT-3500 Power Injector is the WiNRADiO low-noise linear model SF-41.
