Abstract

The invention relates to a method for production of an antenna section comprising a hydrophone (12) for a submarine antenna which may be composed of several antenna sections, whereby the hydrophones are arranged in a row one behind the other in a rectangular cavity (20) at a separation from each other on the inner wall of the cavity and the cavity is filled with a liquid gel (19) to fix the hydrophones, which thickens after introduction. According to the invention, the assembly procedure for the introduction and positioning of the hydrophones may be simplified whereby each hydrophone is inserted and fixed in the cavity with the longitudinal axis thereof essentially vertical, at a given separation from the previously inserted hydrophone, by means of a pipette (16). Liquid gel is then introduced into the cavity to such an amount that the liquid gel at least partly encloses the hydrophone held by the pipette. After the applied gel has thickened the pipette is withdrawn from the cavity for the insertion of another hydrophone, whereupon the method steps are repeated until the required number of hydrophones are inserted in the cavity.
