The transmitter is the fifth generation of digital broadcasting TV transmitting equipment, which is compliant with main standards.

The equipment is composed of digital exciters, intelligent monitoring system, synthesizers, power amplifiers, filter, directional couplers, switching power supplies, lightning protection systems. Each unit is independent, high modularization, nice appearance, easy operation and maintenance.

Hooray 2KW-3KW UHF Terrestrial DTV Transmitters has great variety of products, and inherit the high performance, high stability and high reliability of Hooray’s branded product series. It may work in any frequency within UHF span, and the transmitting bandwidth can be up to 80Mhz. In co-operation with our latest technologies of RF delay and co-channel interference rejection, this system can fulfill the needs of multi-frequency simultaneous transmission and large area coverage, especially suitable for wide coverage terrestrial DTV network in areas with complex local terrain.

This series of products with advance design and simplified architecture are small in size, with the advantage of lower noise, higher efficiency and outstanding anti-interference performance; support DVB-T, DVB-T2, DVB-C, DVB-S, DTMB and other various modulation modes, thus have great flexibility and suitability in actual deployment.
