How to receive DTT Signals & How to Install DVBT2 System?

As you know Doordarshan stopped old analog traditional transmission in main cities. So from now if you want to watch the Doordarshan National channel or other Doordarshan channels like DD News, DD HD, and other TV channels then It requires an ordinary antenna (indoor or outdoor depending upon your location) as used in analog terrestrial TV. But now with the existing TV set, a DVB - T2 Set Top Box is required.

Some integrated Digital TV sets (iDTV) are available in the market having an in-built set-top box or DVB-T2 tuner. Only an antenna to be connected to the TV set for watching DTT (DVB-T2) channels.

DVB-T2 (DTT) signals are typically broadcasted by big TV towers (like TV towers for analog reception) on VHF or UHF frequencies over the air. DVB-T2 signals can be part of the VHF or UHF spectrum. So many countries are moving to this new technology due to its high-quality digital picture quality and digital sound.
