Product Description

DAYTAI Indoor DVB-T Digital Transmitter,(DT-DVB-T-IDT) is a professional DVB-(T)/ATSC digital transmitter researched and 

developed, which gives sustained power output. Its compact structure design has greatly saved space for your room. It is

 applicable to both SFN and MFN network modes and supports both signal-carrier mode and multi carrier-mode. Signal 

channel and broadband transmission are supported.The frequency range of DT-DVB-T-IDT is from 470MHz~806MHz. 

This transmitter has a very high linear and high reliability as it takes high gain and high linear LDMOS tube amplifier 

module. Furthermore, it supports AGC function to keep sustained power output. DT-DVB-T-IDT DVB-(T)/ATSC 

digital transmitter can be widely used in HD/SD digital TV signal transmitting and broadcasting system.


Features

⊙Support fault self-diagnosis

⊙Support MFN and SFN system

⊙Easy to install, elegant appearance

⊙Enhanced signal transmission quality

⊙LED on the front panel support alarm and signal monitor

⊙Stabilized-power supply with wide range of voltage and high efficiency

⊙Multi lightning protection measures, good protection for whole equipment.

⊙24-hour working unmanned, user friendly design

⊙Intelligent and modularized amplifier unit, takes high power gain and high linear

   LDMOS tube amplifier module design

⊙Low power consumption and super linear design to improve the transmission power,

   and reduce the nonlinear distortion

⊙Support AGC function with sustained power output to allow the transmitter

   a good stability and reliability
