How far is digital terrestrial TV coverage?
The factors affecting the signal coverage include the height of the transmitter, the antenna height of the receiver, whether there is occlusion in the center, that is, the sight distance, the transmitted power and so on.If the launch tower 400 meters high, your antenna 2 meters high, 90 km distance just to receive (without considering transmission power).To transmit 90 km, the main station transmit power at least 5KW digital power. Or build a relay station next to the point of fire.

For television, it is necessary to have the ability to receive digital terrestrial television signals. If it is an old analog TV, it can also be accepted by a special set-top box, and then converted to analog signals to be connected to the TV set.Digital television technology is generally divided into three types: digital cable TV, satellite digital TV and terrestrial digital TV, and different broadcasting standards in different parts of the world.
