Scientific paper

A dual-frequency feed designed for use at the prime focus of seven 8.5 m paraboloids used in the synthesis telescope at the Dominion Radio Astrophysical Observatory is described. Efficient dual-mode performance at 1429 MHz results from the combination of modes in a circular waveguide of diameter 0.91 lambda(1420) and a surrounding cavity of diameter 2.6 lambda(1420). Satisfactory 408 MHz performance is obtained in a feed of depth only 0.55 lambda(408) without significant effect on 1420 MHz performance.
