Abstract
A study of atmospheric-induced fading on 23 km links at 9.6, 11.4, and 28.8 GHz near Boulder, CO, is described. Height-gain observations and refractivity profile measurements were obtained using a 300 m tower as one end of the links. Observations were obtained when the vertical refractive index profile was smooth and when it displayed significant variations in gradient. Narrow beam and wide beam receiving antennas were used for comparison of relative performance during fading. Fading types which result from atmospheric ray bending are listed and characterized. Examples of the different fading types observed, e.g., atmospheric multipath and radio holes, are presented.
