Product Description
Single Way CATV Bridging Amplifier
General Descriptions:
1. Suitable for trunk and branch trunk amplification in single-way CATV system;
2. With one trunk output port and two bridge output port, used for trunk branching and building amplification;
3. Using double plug-in power module(made by PHILIPS or Motorola) to make upgrade easy; Manual gain control and two degrees slope control;
4. Provide two power supply method, centralized(AC30~60V) or individual (AC220V);
5. Waterproof and dustproof design, fast heat dissipation and fine screening characteristic;
6. Plug-in temperature compensator for selection;
7. High capability to price ratio.
