WiNRADiO WR-BT-650 HF/VHF Power Injector (Bias 'T')
Оценить
This device provides a means of injecting 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 20 kHz to 650 MHz.

The WiNRADiO WR-BT-650 Power Injector is especially suitable for use with WiNRADiO AX-81S Active HF Antenna.

WiNRADiO WR-BT-650 Power Injector Features

 Frequency range 0.02 to 650 MHz 
 Flat frequency response 
 Low insertion loss 
 Wide range of DC voltages 
 Rugged weatherproof construction 
 Simple installation

Installation

WR-BT-650 Power Injector Installation In this example, an active antenna (such as the AX-81S antenna) is powered via the coaxial cable. On the receiver side, the power is injected in the coaxial cable using the WiNRADiO WR-BT-650 Bias 'T' device. Such arrangement makes it possible to conveniently power the antenna via the coaxial cable and eliminate additional wiring.

A suitable 12 V power supply to use with the WR-BT-650 Power Injector is the WiNRADiO low-noise linear model SF-41.
