Abstract

This letter presents the results of a study on rain attenuation of an outdoor radio propagation channel at 26 GHz, which is widely used for local multipoint distribution service deployment. The difference in attenuation between vertical and horizontal polarization is compared for wide-band signals using a line-of-sight radio link with alternate polarizations by transmitting signals with horizontal and vertical polarizations. It is shown that attenuation difference due to depolarization becomes much more significant when the rainfall exceeds 70 mm/h.
