FIELD: radio engineering. ^ SUBSTANCE: dome comprises a single-layer cone-shaped shell and an erosion-resistant tip made of dielectric material, joined to each other by means of an adhesive joint, a metal ring rigidly fixed with the cone-shaped shell, and in the area of cone-shaped shell and tip joint inside there is an intermediate cone-shaped ring made of material same as the tip material and glued along contacting surfaces by a glue on the epoxysiliconorganic base with a filler of powdery oxide ceramics, and a paint and varnish coating is applied onto outer and inner surfaces of the dome. The method to make an antenna dome includes assembly of an antenna dome in a vertical slip with coaxial fixation of the cone-shaped shell, tip, intermediate ring and their adhesion with separate pressing for the cone-shaped shell and the intermediate ring and the tip with specific pressure 0.010.05 MPa and curing for 6872 hours at room temperature or with curing of 22.5 hours at the temperature of 7090C. ^ EFFECT: increased strength of cap attachment to a tip, increased bearing capacity, improved radio engineering properties at higher thermal and power loads. ^ 7 cl, 1 tbl, 4 dwg |
