2.0 - 2.9GHz MMDS 400W DTT Broadband Outdoor Digital TV Transmitter for Wireless Coverage System


HTM-400D 400W MMDS outdoor digital transmitter is a kind of wireless digital TV transmission facility working on S band (2.0-2.9GHz). It supports PAL/SECAM/NTSC standards and multiple digital modulation modes like DVB-S/S2, DVB-T/T2, DVB-C, QAM, ISDB-T/TB and etc. Its AGC/ALC function guaranteed the reliable operation of the equipment by maintain constant power output of transmitter. It also has auto-alarming and lightning-proof functions. Its optional GSM message module can tell you the parameters of output power, working voltage and AGC, can monitor the abnormal values real-time. As the advantages mentioned above, this equipment can widely apply to point to point and point to multi-point transmission and signal coverage. It can be used as digital signal coverage system. Besides, it is also to trunk transmission of TV signal source.


All its features make it outstanding in operational reliability and cost performance.


Main features:

· The design of outdoor proof and all-in-one machine makes waveguide unneeded, system investment economic and the effective coverage and transmission range increased.

· With superlinear design of power amplifier, transmitting power has been increased and unlinear distortion has been effectively decreased.

· With natural heat dissipation or forced air cooling design, equipment operational reliability can be improved.

· With door design, signal debugging and equipment maintenance can be simply carried out.

· With simple debugging procedure, signal opening can be achieved without specialized instruments.

· With multiple choices in power level and local frequency.

· With extended interface for remote control and GSM message auto-alarm system (optional), concentrated monitoring can be achieved.
