Dual Band Line Amplifier

20dB Gain

Product Overview

This JDTECK Dual Band Band Line Amplifier was designed specifically to provide a boost in signal downstream of a cellular repeater on a DAS in order to extend in-building coverage where signal may drop off due to long coaxial runs.  It is designed to be installed after a repeater, not before as it has DL output but 0dB UL power. It also has gain in both directions.  It features alarm monitoring LED's to indicate error detection in the respective frequency band.  

A test report is included with each line amp so you are assured of quality standards. 

  • Extend In-Building Coverage Economically!
  • Full Duplex Gain (20dB)
  • Alarm Monitoring LED's for Error Detection
  • Meets ETSI & 3GPP / 3GPP2 Standards
  • Supports Quad Band Frequencies- USA
  • Provides DL Output Power Only (0dB on the UL)
  • 36 Months Warranty
  • Supports 90-265 Volt Input
  • Light-Weight
  • Attractive Design
