TV Gap Filter (TV Repeater)

TV Gap Filter: 1. Output: 10MW~500MW, 1W-10W, 20W-50W, 100W-200W 2. Low cost 3. Self-excitation protection

KFZF-Ⅰ-850 TV Gap Filter, 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.
