Abstract: An experimental study of atmospheric multipath on a 23 km link at 9.6 and 28.8 GHz near Boulder, Colorado, is described. The preliminary observations were made for three days in July 1979 when a strong inversion layer was present, creating an elevated tropospheric duct. The possible influence of antenna aperture size on atmospheric multipath was investigated by observing fades and enhancements on the 28.8 GHz carrier using a 10° horn and a 1.2° parabolic dish. Continuous height-gain observations were obtained using the 300 m. tower at Erie, Colorado, as one end of the link. Meteorological data at the tower were also recorded during observation periods of the radio signal.
