FIELD: fish-search or geophysical equipment. SUBSTANCE: antenna has linear converter units in the form of sealed compound-filled tubes accommodating cylindrical piezoids, electric communication lines, and converter fastenings. Novelty is that antenna has cylindrical metal case with windows accommodating mentioned converters. Antenna case is filled with compound and is made in the form of rectangular frame of tubes some of which have branch tubes with linear units attached to them through acoustic isolators. Some of tubes are filled with air to provide buoyancy. EFFECT: enlarged functional capabilities. |
