OPTIMUM WORKING FREQUENCY (fot) is the most practical operating frequency and the one
that can be relied on to have the fewest problems.
PRECIPITATION ATTENUATION can be caused by rain, fog, snow, and hail; and can affect
overall communications considerably.
TEMPERATURE INVERSION causes channels, or ducts, of cool air to form between layers of
warm air, which can cause radio waves to travel far beyond the normal line-of-sight distances.
TROPOSPHERIC PROPAGATION uses the scattering principle to achieve beyond the
line-of-sight radio communications within the troposphere.
