Abstract
Preliminary findings are presented from a study to determine the mutual interference between linear crosspolarised radio channels at 11 GHz over an 8½-mile path. In particular, severe crosspolarising effects were encountered when antenna primary-feed apertures were artificially wetted or allowed to become wet during rain and snow. Significantly improved values of isolation between channels have been measured under heavy rainfall with the antennas protected from rain.
