Abstract
Subreflectors on DSN antennas have historically been of formed and welded sheet metal construction, which is quite costly. Flame-spray metallized fiberglass-epoxy offers an alternative technique at much lower cost. This article presents results of a study to show that system noise temperature would be increased about 0.3 K at X-band when using the alternate material. Additional testing, however, is required to evaluate weathering and noise generation while diplexing at high power.
