  • 7.1 Propogation Types


    What type of propagation usually occurs from one hand- held VHF transceiver to another nearby?
    Tunnel propagation
    Sky-wave propagation
    Auroral propagation
    Line-of-sight propagation

    How does the range of sky-wave propagation compare to ground- wave propagation?
    It is much shorter
    It is about the same
    It depends on the weather
    It is much longer

    When a signal is returned to earth by the ionosphere, what is this called?
    Tropospheric propagation
    Ground-wave propagation
    Sky-wave propagation
    Earth-moon-earth propagation

    How are VHF signals propagated within the range of the visible horizon?
    By direct wave
    By sky wave
    By plane wave
    By geometric wave

    Skywave is another name for:
    ionospheric wave
    tropospheric wave
    ground wave
    inverted wave

    That portion of the radiation which is directly affected by the surface of the earth is called:
    tropospheric wave
    ionospheric wave
    inverted wave
    ground wave

    At HF frequencies, line-of-sight transmission between two stations uses mainly the:
    skip wave
    ground wave

    The distance travelled by ground waves:
    depends on the maximum usable frequency
    is more at higher frequencies
    is less at higher frequencies
    is the same for all frequencies

    The radio wave which follows a path from the transmitter to the ionosphere and back to earth is known correctly as the:
    F layer
    surface wave
    ionospheric wave
    skip wave

    Reception of high frequency (HF) radio waves beyond 4000 km is generally possible by:
    ground wave
    ionospheric wave
    skip wave
    surface wave
