Abstract
This paper presents the results of a 30 Mcjs survey of the southern sky using the 210 ft steerable reflector at Parkes, N.S.W. The aerial was fed by a right-handed helix with plane reflector giving a tapered illumination that fell to approximately 10% at the edge of the aperture. The resulting main beam was circular and approximately 11 0 between half-power points. The aerial measured left-handed circular polarization relative to the direction of propagation.Keywords
