Patent ID: 8400878

Claim:
Electroacoustic underwater antenna comprising: a reflector ( 11 ); spring elements which fix the reflector ( 11 ) on an antenna mount ( 10 ), in particular on a hull of a submarine, and which act on the reflector ( 11 ) close to its upper and lower longitudinal edges in a mounted position of the reflector and a transducer arrangement ( 17 ) comprising electroacoustic transducers mounted to the reflector ( 11 ), characterized in that the spring elements have an upper and a lower resilient rocker ( 19 , 20 ), each rocker ( 19 , 20 ) extending over the horizontal extent of the reflector ( 11 ) in the mounted position and having a front contact limb ( 191 , 201 ) for contacting the reflector ( 11 ) and for fixing the spring elements to the reflector ( 11 ), and wherein each rocker ( 19 , 20 ) has a rear contact limb ( 192 , 202 ) for contacting the antenna mount ( 10 ) and for fixing the spring elements to the antenna mount ( 10 ), and wherein the upper rocker ( 19 ) has an approximately U-shaped profile and the lower rocker ( 20 ) has a profile which is formed from two U-shaped end sections, each section comprising only one of the contact limbs ( 201 , 202 ), and an extended centre section ( 203 ) connecting the end sections integrally; and wherein a space between the upper and lower rockers ( 19 , 20 ) is filled with a buoyant body ( 21 ), wherein, on the other hand, the buoyant body ( 21 ) extends to the antenna mount ( 10 ) and, on the other hand, the body extends to a position spaced from the reflector ( 11 ).
