Abstract
A re-examination of the problems of shaping dual offset reflectors to produce a zero-crosspolarised parallel beam shows that the shaping can, under geometrical optics, compensate not only for the system asymmetry, but also for a certain amount of crosspolarisation in the feed pattern.Keywords
