  • Abstract
    Cassegrain operation of moderate-sized antennas at low frequencies often poses difficulties because of the large feed horn required. Primary-focus operation using a two-hybrid-mode feed horn is shown to give a G/T ratio close to that provided by classical Cassegrain operation using a single-hybrid-mode feed.
