500W Low Power UHF Terrestrial DTV Transmitter
Gospell’s GT-5900-500 Series is a low power UHF terrestrial DTV transmitter, which inherits the high performance, high stability and high reliability of Gospell’s many products. It can work in any frequency within UHF span, and the transmitting bandwidth is up to 80MHz. By incorporating our latest technologies of linear and non-linear digital adaptive pre-correction, RF delay and co-channel interference rejection, this system can fulfill the needs of single band or broadband transmission in small to medium-scale terrestrial coverage scenarios.
This series of products, which has advance design and simplified architecture are small in size, with the advantage of lower noise, higher efficiency, and outstanding anti-interference performance. They support DVB-T/H, DTMB, ATSC, ISDB-T/Tb and DVB-T2 standards, thus having greater flexibility and suitability in actual deployment.
