Product Description

Amplification part adopts British OEI-F**6 gallium arsenide amplifier chip with low noise ratio, non-linear distortion and none lose and output of forward and reverse signal. It also has aluminum and zinc die-casting structure with better shield and heat dissipation effect. In addition, the power supply is *0V or **0V with anti-surging switching power supply.
HDU is the mark of HFC two-way network household distribution unit. **0 stands for downlink to ***0MHz, suffix 2 means 2 routes output and 4 is 4 routes output.
