Quad Band Line Amp

With MGC -20dBm

Product Overview

This JDTECK Quad 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.  

Also built into this line amp are DIP switches that manually attenuate the gain of the respective frequency band. This is especially convenient when you only need to attenuate one or two frequencies while others need to be left at full gain. 

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