  2. Terminator (solar) - Wikipedia

    en.wikipedia.org/wiki/Terminator_(solar)

    This time-difference puts the ionosphere into a unique intermediate state along the terminator, called the "grey line". [5] Amateur radio operators take advantage of conditions along the terminator to perform long-distance communications. Called "gray-line" or "grey-line" propagation, this signal path is a type of skywave propagation.

  3. 80-meter band - Wikipedia

    en.wikipedia.org/wiki/80-meter_band

    At times, there is pronounced dark-side gray-line propagation, which is most useful on polar routes, away from equatorial thunderstorm activity. At higher latitudes, a noticeable skip zone sometimes appears on the band during nighttime hours in midwinter, which can be as much as 300 miles / 500 km, rendering communication with closer stations ...

  4. Radio propagation - Wikipedia

    en.wikipedia.org/wiki/Radio_propagation

    Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere. [1]: 26‑1 As a form of electromagnetic radiation, like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and scattering. [2]

  5. Diurnal phase shift - Wikipedia

    en.wikipedia.org/wiki/Diurnal_phase_shift

    In telecommunications, diurnal phase shift is the phase shift of electromagnetic signals associated with daily changes in the ionosphere.The major changes usually occur during the period of time when sunrise or sunset is present at critical points along the path.

  6. Line-of-sight propagation - Wikipedia

    en.wikipedia.org/wiki/Line-of-sight_propagation

    Line of sight (LoS) propagation from an antenna. Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves can only travel in a direct visual path from the source to the receiver without obstacles. [1] Electromagnetic transmission includes light emissions traveling in a straight line.

  7. Sporadic E propagation - Wikipedia

    en.wikipedia.org/wiki/Sporadic_E_propagation

    Sporadic E (abbreviated E s or SpE) is an uncommon form of radio propagation using a low level of the Earth's ionosphere that normally does not refract radio waves above about 15 MHz. Sporadic E propagation reflects signals off relatively small ionization patches in the lower E region located at altitudes of about 95~120 km (50~75 miles).

  9. Log-distance path loss model - Wikipedia

    en.wikipedia.org/wiki/Log-distance_path_loss_model

    The log-distance path loss model is a radio propagation model that predicts the path loss a signal encounters inside a building or densely populated areas over long distance. While the log-distance model is suitable for longer distances, the short-distance path loss model is often used for indoor environments or very short outdoor distances.
