400W UHF Terrestrial Indoor Digital TV Transmitter With DVB-T/H,
DVB-T2, ATSC, DTMB and ISDB-T/Tb
HTU-400I works on UHF band (470-860MHz).It is a kind of
product(meet euro-standard) that specially designed to supply
common or pilot frequency coverage and subsidiary station by
consuming small and medium power for terrestrial digital TV
transmission. It applies to modulation modes like DVB-S, DVB-S2,
QAM, DVB-T, DVB-T2 and DTMB-T and so on. It is applicable to
built-up areas, basement, tunnel and remote mountainous areas. Its
main advantages include installation convenience and simple process
in debugging and maintenance, etc. And in any combination of
multiple antenna-feeder system it can supply local coverage and
subsidiary station of wireless digital signal in the blind area.
1. Wide-band frequency response and low noise design.
2. Design of low power consumption and linearization advances
emitting power of the transmitter and reduces nonlinear distortion.
3. Very low group delay feature, suitable for digital signal
4. ALC keeps output of constant power, output VSWR detecting
5. Apply to single-channel or multi-channel UHF digital television
6. Be used in the Wide-band frequency repeating of HFC, or MMDS
digital TV signal.
7. Realize wireless network coverage of digital TV at a low cost.
8. Modular design simplifies installation, field services and
9. Automatic and manual switching backup systems available.
10. Build-in lightning protector with current-dividing series power
prevents lighting surge and instant overvoltage.
11. Indoor type with large LCD panel system real time working
condition, maintenance and management of system can be achieved
12. Indoor type adopts indoor waterproof design and inside SMS
module to realize real-time wireless remote monitoring (Optional)
