Digital TV Signal Emitter

Digital TV Signal Emitter
Product Detailed
Broadcast Digital TV Signal Emitter features: 1. AGC and ALC 2. OMC software 3. Modular structure 4. Multiple pretections

KFZF-Ⅰ-850  broadcast digital TV emitter series digital TV transmitter, is the fourth generation of terrestrial digital broadcasting TV transmitting equipment, which compliant with GB20600-2006 (China Framing Structure, Channel Coding and Modulation for Digital Terrestrial Television Broadcasting System), GB/T14433-1993 (Technical Specifications for Coverage Networks of Color TV Broadcasting), and GY/T229.4-2008 (Technical Specifications and Methods of Measurement for Digital Terrestrial Television Broadcasting Transmitters) standards.

The equipment is special for digital TV signal supplementary coverage.

Main Features:

1. Low cost digital TV signal supplementary coverage, it can be easily set uprightly at the floor or hanged on the wall.

2. Self-excitation protection, use AGC and ALC technologies to ensure stability;

3. Stable and reliable remote monitoring and control function, support configure and inquiry by OMC software.

4. Well designed integral radiating design, moisture and corrosion protection.

5. Modular structure, easy installation and maintenance.

6. Adopts strict cavity filter, ensure perfect out-band suppression.

7. Multiple power supplies, -48VDC, AC220V or solar energy power source.

8. Supports over-voltage, over-current and lightning protections, optional backup battery.
