Description

This bias tee box is used to insert AC or DC power into an HF signal to power remote antenna preamplifiers (DC), Bi-directional beverages (AC) or other devices. It is usually positioned at the receiving end of the coaxial cable to pass AC or DC power from an external source to the coaxial cable running to powered device. A bias tee consists of a feed inductor to deliver AC/DC to a connector on the device side and a blocking capacitor to keep power supply from passing through to the receiver. Bias tees are used in a variety of applications, but are generally used to provide an RF signal and power to a remote device where running two separate cables would not be advantageous. This box offers something more like: protections, variable attenuator and input common-mode filter.


Using

  • Providing an RF signal and (AC or DC) power to a remote device over one coax
  • You can use bias tee BOX on both sides as power IN and OUT from RF coax
  • FOR: preamplifiers, Bi-dir beverages, 4-way antenna switch etc

Main functions

  • Broadband: 0.1 MHz to 60 MHz
  • Variable ATTENUATOR - image
  • Front-end protection with diodes - image
  • Power supply common-mode filter
  • Power supply short protection
  • High voltage and current protections
  • LED diode indication of AC/DC power on the coax
  • You can set ATT when you have too high gain of preamp
  • Quality connectors
  • IP56 box - recommended to protect it against water
  • Feeder size 100x100 mm
  • ASSEMBLED VERSION

Parameters

  • Supply voltage AC/DC up to 24 V
  • Supply current up to 500 mA
  • Insert loss lower than 1 dB - for minimal ATT
