What Is Long Wave?

- Jun 20, 2018-

The long wave is a wireless cable wave with a frequency from 300 kHz to 30 Hz. Its propagation mode is not mainly spread around the surface of the ground ring as ionospheric waves. Its effect range is from several thousand to tens of thousands of kilometers. In addition, at close range (200 Within 300 km, it can also be transmitted by ground waves. The electric field intensity in the band is greater at night than in daytime. The shorter the wavelength, the greater the increase; the electric field intensity is less affected by the season; the propagation conditions are less affected by the ionospheric disturbance and stable. Good sex, will not result in rapid changes in the strength of state balance acceptance and sudden interruption of communication.
