FIELD: antennae.
SUBSTANCE: invention relates to antenna engineering and can be used in antenna posts of submarines. Antenna dome consists of a fiberglass shell, a hollow gap, a sitall (ceramized glass) shell, a reservoir for liquid, a piston and a spring, herewith on the outer side of the dome there is an additional layer of an elastic material installed with clearance n×λ/4 (where n is an odd integer number, starting with 1, λ is the wavelength), filled with liquid, the pressure of which is equal to the submergence pressure, herewith to allow free circulation of the sea water the outer layer is made with perforation.
EFFECT: technical result is provision of impact strength in motion, immersion, surfacing and resistance to the effect of shock wave.
