The waves have a frequency of about Hertz electromagnetic waves with high frequency of this size is not reflected at the ionosphere layers, but it passes through the atmosphere to outer world. Therefore, the wave will require sight tv stations convey periodically receive waves waves from transmission stations, which comes in a straight line, and then expand the signal strength before they are sent to the next available station because the signal travels in a straight line, so the signal will go.Only about 80 km on the Earth's surface only. This is because the Earth's surface curvature, or may use a wave-microwave signal from the station, sent to the satellite, which orbits are in orbit at stationary positions, compared to a particular location on the Earth's surface, that is, the satellite with the same angular velocity speed of rotation of the Earth. Then-star de t wave to the preparation to receive the station in the distance.
