How does the TV receive terrestrial digital signals over long distances?

Date:Jan 24, 2019

Due to the popularity of satellite broadcasting, cable television and network distribution, TV differences in each region are getting smaller and smaller. However, the reception environment for terrestrial digital broadcasting is still very important.

If you can receive radio signal from a transmitting station that is far away from the local station, you will be able to see programs that are not broadcast locally. Even the kind of paid broadcasts that need to pay for money. Or at the station, near the radio wave output, because of the geographical conditions, if the surrounding environment has a great impact on the radiation, there is no way to receive radio waves. A successful digital ground long-distance reception probability has a technique that can make up for it.

For terrestrial digital remote reception, high-performance antennas can be used to adjust the direction of the antenna, as well as tuners and boosters with high receiver sensitivity.


A typical UHF band antenna should have approximately 14 Oscillators. This was changed to 20 to 30 Oscillator antennas. The more Oscillator, the more directional adjustment becomes more directional, and it is easier to capture weak radio waves.

In this case, it is better to use the level checker. Since the signal quality can be visualized by the intensity of the radio waves, it is easier to find the best position.

Enhancers can be used to increase weak radio waves, but long-distance reception on the ground digital needs to consider the use of woods, buildings. Because it amplifies noise, it can adversely affect neighboring sites. It amplifies the weak radio waves utilized by a particular repeater station.
