DTV Transmitter Describe

We can provide efficient, broadband DTV transmitters with output power ranging from 50W to 7KW.The frequency bands include UHF and VHF; Modulation methods include DTMB/DVB-T/DVB-T2, etc. Cooling methods include air cooling and liquid cooling. It can be designed as both outdoor and indoor types according to practical needs. At the same time, one cabinet with multiple machines can be designed, such as one cabinet with dual machines, one cabinet with three machines, and one cabinet with five machines, to save equipment installation space. We can provide solutions and related equipment for 1+1 primary and backup machines or N+1 primary and backup machines. We can also provide outdoor type repeaters, bandpass filters, multiplexers, antennas, antenna switches, N+1 control devices, TS switching distributors, monitoring software, etc. for the corresponding frequency bands of DTV transmitters.
