Abstract
The results of a rigorous analysis of the DSN 70-m antenna S-band (2.295-GHz) RF performance are presented. Previous estimation of 1.6 dB S-band gain improvement of the 70-m antenna over the 64-m antenna has been revised to 1.5 dB by this analysis. The S-band RCP beam position offset relative to X-band (8.45-GHz) beam position is predicted to be 0.0045° (0.04 beamwidth). The effective S-band gain loss resulting from non-coincidence with the X-band beam is predicted to be 0.02 dB. Therefore, this is no longer a concern for the 64-m to 70-m upgrade project.
