Abstract
The last of a series of three articles on the subject, this final paint study article presents excess noise temperatures and added-gain losses at 32 GHz for various combinations of paints and primers currently being studied for use on DSN antenna reflector surfaces. It is shown that 500FHR6 acrylic urethane-based paint has the lowest excess noise-temperature contribution and should be used for all new DSN beam-waveguide antennas being constructed and for all those 34-m and 70-m antennas whose reflector surfaces need repainting.
