Results of XPD site-diversity measurements at 11.8 GHz
Abstract
A site diversity experiment which used the OTS satellite to measure cross polarization discrimination (XPD) improvement is reported. Results are presented from the period April, 1979-December, 1980 from two sites using 3 m Cassegrain antennas in Denmark. The time percentages for a mean single station were compared with the site diversity figures, and an improvement of 77 was obtained at 23 dB XPD, and 385 at 21 XPD. The worst site diversity XPD levels which were encountered were 20-22 dB and were associated with heavy rain and thunder showers.
