CATV BI-Direction Trunk Amplifier

Features: 1) Adopts Philips or Motorola imported high-gain module to amplify 2) Equalizer, attenuator have fixed and adjustable structure for selection 3) Suitable for large or middle-size bi-directional network main trunk signal transmission, can substitute imported and famous brand machine 4) Forward and reverse fore-and-aft have independent test port, easy to debug 5) Return channel adopt Philips or Motorola amplify module, good quality duplex filter, plug fixed attenuators and equalizers 6) Output splitter or coupler can plug change to make engineering debug more agile Parameter Type H 500-450.
