The GOSPELL’s GT-5900-OD is a product series of outdoor type UHF Digital Terrestrial Television (DTT) transmitters, and be designed for blink areas coverage and (or) repeater application in DTT network. The series has combined lots of excellent design concepts from our rich experience in practical network deployment, bring service provider a network with superior efficiency, stability and reliability. The series support various modulation standards of digital terrestrial television, such as DVB-T/H, DVB-T2, DTMB, ATSC, ISDB-T, also it could be operating in SFN mode for less occupied frequency resource.
The GT-5900-OD series support SNMP based management and maintenance for controls and remote status monitoring, this can significantly reduce management time and operating expense (OPEX). In co-operation with latest technologies of RF delay and co-channel interference rejection, this system can fulfill the needs of broadband transmission of SD and HD digital television programs, especially suitable for small/medium-scale coverage areas with complex terrains.
Features:
- Supports pole mounted, for superior power efficiency.
- Supports frequency range from 470MHz to 860MHz.
- Supports up to 80MHz of transmitting bandwidth within UHF span.
- Single channel or broadband transmission.
- Supports various kinds of incoming modulated signal sources which from UHF, MMDS, fiber.
- Excellent design in heat dissipation and weather-proof for long time operation in harsh environments.
- Aluminum alloy housing and sealed connector design for excellent anti-interference performance.
- Low power consumption with linear design, further improves transmitting power and minimize the non-linear distortion.
- Extreme low group delay for DTV signal transmission.
- Large and dynamic Auto Gain Control (AGC) circuit ensures stability of output power.
- Modular design for convenient installation, on-site maintenance and power upgrading.
- Supports various of protection measures, such as over excitation, over-current, over-temperature, lighting-proof and VSWR protections.
- Supports local and remote management and maintenance via RS-485, TCP/IP, GPRS network.
