Abstract:
1. A method for production of an antenna section, which has hydrophones at a distance from one another, for an underwater antenna which can be assembled from a plurality of antenna sections, in which the hydrophones are introduced in a row one behind the other into an elongated cavity, at a distance from one another and at a distance from the inner wall of the cavity, and the cavity is filled with a liquid gel in order to fix the hydrophones, which liquid gel forms a gel after being introduced, wherein each hydrophone is inserted and held approximately centrally by means of a suction lifter into the cavity, whose longitudinal axis is aligned essentially vertically, at a predetermined distance from the previously inserted hydrophone, an amount of liquid gel is then introduced into the cavity such that the liquid gel at least partially surrounds the hydrophone which is being held by the suction lifter, and, once the gel which has been introduced has formed a gel, the suction lifter is removed from the cavity for insertion of a next hydrophone and, these method steps are repeated until the predetermined number of hydrophones have been placed in the cavity.
