Abstract

An antenna module for a sonar device which is installed on board a marine vessel has a hollow antenna mount (11) which is designed to be arranged on the vessel hull, and has at least one underwater antenna (12, 13) with a housing (14, 15) that is held on the antenna mount (11), and with a transducer arrangement (16, 17) which is accommodated in the housing (14, 15). In order to ensure reliable protection of the antenna module against the ingress of water into the internal areas of the housing (14, 15) and antenna mount (11) which are filled with electronics and signal lines, those internal areas of the antenna mount (11) and housing (14, 15) which are connected to one another are subjected to a gas pressure, preferably an air pressure, which is higher than the hydrostatic pressure at the operational depth of the antenna module. A pressure sensor (24) monitors the gas pressure and generates a warning signal in the event of the gas pressure falling because of leaks.
