Abstract :
A model describing the effect of a sand/dust accretion on the aperture field and gain of a reflector antenna is checked experimentally and extended to predict enhanced crosspolarisation. The largest effects theoretically occur for accretion layers that are uniformly thick but only cover part of the reflector.
