Measurements of crosspolarisation and gain reduction due to dust on a microwave reflector antenna
Abstract
9 GHz measurements of effects of dust accretion on the surface of a reflector antenna confirm an earlier prediction of a larger gain reduction when the dust layer covers half the area. Crosspolarization levels were higher than expected theoretically. Deposits on the primary feed also cause high crosspolarization.
