Abstract
This article discusses the development of a net designed to keeps birds out of the 34-m beam-waveguide antenna opening on the dish surface. Test results on a prototype net showed that the net did not deteriorate when 20 kW at 7.165 GHz were transmitted through it. When dry, the worst-case net contribution to the system-noise temperature was measured to be 0.04 K and 0.18 K at 8.425 GHz and 32 GHz, respectively. When wet, the worst-case net contributions were 0.4 K at 8.425 GHz and 3 K at 32 GHz.
