Abstract

In the case of an electroacoustic underwater antenna, which has a reflector (11) and spring elements which fix the reflector (11) on an antenna mount (10), in particular on the hull of a submarine, in order to produce an underwater antenna which can be produced at low cost from only a small number of components, and in which the reflector (11) to which electroacoustic transducers are fitted is at an adequate distance from the antenna mount (10), is acoustically well decoupled from the antenna mount (10) and is largely resistant to shock loading, the spring elements have an upper and a lower resilient rocker (19, 20), wherein each rocker (19, 20) extends over the horizontal extent of the reflector (11) in the fitted position. Each rocker (19, 20) has a rear contact limb (192, 202), for making contact with and fixing on the antenna mount (10), and a front contact limb (191, 201), for making contact with and fixing on the reflector (11).
