SEALED HOUSING PROTECTING REFLECTOR-TYPE ANTENNA Russian patent published in 1998 - IPC

FIELD: radio engineering. SUBSTANCE: sealed housing protecting reflector-type antenna, specifically, apertures of various types of reflector-type antennas against atmospheric precipitation. Cylindrical blister of housing with flange is produced in the form of blister flanging directed inwards and has shape of truncated cone. Flange and protrusion manufactured in the form of ring embracing blister forms barrel that houses radioparent screen. Vertex of truncated cone is flanged towards screen. Embracing band with legs is made elastic and has sealing spacer on its internal surface. One of legs is fabricated in the form of truncated cone directed with vertex towards screen and contacts it, another leg contacts protrusion. EFFECT: simplified design, improved operational reliability. 1 cl, 4 dwg
