Abstract
Attenuation, dispersion and depolarization of 19 and 28 GHz signals from a COMSTAR satellite are measured at Bell Laboratories, Crawford Hill, New Jersey. Cumulative distributions of attenuation for one year are presented. No evidence has been found of variable amplitude or phase dispersion due to multipath or resonances in the propagation medium. The linear polarization o rientation that minimizes depolarization is usually w ithin a few degrees of vertical or horizontal at the earth terminal. Depolari zation for fixed vertically and horizontally polarized signals is very low, usually below -35 dB.
