A dual-band feed system for the Parkes radio telescope

A dual-band, dual-polarisation, coaxial receiver system for 10 cm and 50 cm wavelengths is being designed and constructed for the Parkes radio telescope. While the primary motivation is to provide a receiver system optimised for pulsar observations, the feed system will also be used for other wideband continuum observations, such as the 9 cm transition of CH and various recombination lines.
