Rain-Blowing Plenum For Antenna Feed Horn
Abstract
Double-diaphragm radome drives raindrops away from antenna feed horn. Includes solid diaphragm at mouth of feed horn surmounted by perforated diaphragm. Pressurized air in plenum between diaphragms flows out through perforations. Eliminates increase in noise temperature occuring when water covers radome. Useful for X-band and higher frequencies, susceptible to effects of water.
