The article considers the experience of manufacturing of horn antenna with complex spatial configuration by 3D-printing method (technique), its prototype is a series-produced antenna from the composition of onboard avionics. A prototype antenna has a low manufacturability; its production is associated with a number of complex manufacturing operations. The using of additive technologies lets optimize the construction due to reducing of detail quantity and simplify the production engineering. The article contains the results of the characteristics analysis of produced additive antenna: the analysis of the internal structure of the prototype unit and the measured results of the functional parameters of the additive antenna (standing wave ratio, gain factor, antenna beam width in azimuth and elevation plane) are given. The results of tests of the additive antenna concerning the resistance to environmental factors are provided. Special attention is given to the analysis of the engineering effectiveness of the production making using additive technologies. The received results of the research and experiments have demonstrated that the techniques of the additive manufacturing lead to the production of proper quality which can be used in particular in the special-purpose radio electronic equipment.
