Abstract

1296298 Aerials HOLLANDSE SIGNAALAPPARATEN NV 30 June 1971 [2 July 1970] 30697/71 Heading H4A A procedure for sealing a radiating waveguide aperture is to provide a piece of polytetrafluoroethylene (P.T.F.E.) whose dimensions correspond with those of the aperture, and whose edges have a film of solderable material, and to solder it over the aperture. The film may be constituted by a copper layer over which a leadtin layer is deposited by electro-plating. If the waveguide is made of aluminium, the edges of the aperture may be bronzed and then provided with an electro-plated lead-tin layer.
