    The electric and magnetic lines of force of a radio wave are perpendicular to the earth's surface
    The electric lines of force of a radio wave are perpendicular to the earth's surface
    The electric lines of force of a radio wave are parallel to the earth's surface
    The magnetic lines of force of a radio wave are parallel to the earth's surface

    B-006-07-02
    What does vertical wave polarization mean?
    The magnetic lines of force of a radio wave are perpendicular to the earth's surface
    The electric lines of force of a radio wave are perpendicular to the earth's surface
    The electric and magnetic lines of force of a radio wave are parallel to the earth's surface
    The electric lines of force of a radio wave are parallel to the earth's surface

    B-006-07-03
    What electromagnetic wave polarization does a Yagi antenna have when its elements are parallel to the earth's surface?
    Helical
    Horizontal
    Vertical
    Circular

    B-006-07-04
    What electromagnetic wave polarization does a half-wavelength antenna have when it is perpendicular to the earth's surface?
    Circular
    Horizontal
    Parabolical
    Vertical

    B-006-07-05
    Polarization of an antenna is determined by:
    the height of the antenna
    the electric field
    the type of antenna
    the magnetic field

    B-006-07-06
    An isotropic antenna is a:
    hypothetical point source
    infinitely long piece of wire
    dummy load
    half-wave reference dipole

    B-006-07-07
    What is the antenna radiation pattern for an isotropic radiator?
    A parabola
    A cardioid
    A unidirectional cardioid
    A sphere

    B-006-07-08
    VHF signals from a mobile station using a vertical whip antenna will normally be best received using a:
    random length of wire
    horizontal ground-plane antenna
    vertical ground-plane antenna
    horizontal dipole antenna

    B-006-07-09
    A dipole antenna will emit a vertically polarized wave if it is:
    fed with the correct type of RF
    too near to the ground
    parallel with the ground
    mounted vertically

    B-006-07-10
    If an electromagnetic wave leaves an antenna vertically polarized, it will arrive at the receiving antenna, by ground wave:
    polarized at right angles to original
    vertically polarized
    horizontally polarized
    polarized in any plane

    B-006-07-11
    Compared with a horizontal antenna, a vertical antenna will receive a vertically polarized radio wave:
    at weaker strength
    without any comparative difference
    if the antenna changes the polarization
    at greater strength
