Abstract
In support of the Mariner 1973 X-band experiment, it is necessary to provide the DSS 14 64-meter-diameter antenna with a dual-frequency microwave feed system. To fulfill this requirement, a particularly attractive approach, the reflex feed system, has been implemented. Completion of the reflex feed installation into the DSS 14 antenna was accomplished on January 24, 1973. The performance of this system was evaluated during the period of January 25, 1973, through January 30, 1973. This evaluation established the reflex feed system performance as completely acceptable to the Mariner 1973 X-band experiment. In two cases, S-band antenna gain and S-band system noise temperature, the reflex feed system performance is actually superior to the standard S-band feed system. In this reporting the feed system design is briefly reviewed, including a new dichroic reflector developed at JPL, and the performance measurement data are presented.
