Zusammenfassung:	FIELD: emergency radio communication systems on board ships and surface facilities. SUBSTANCE: system has hollow metal cylinders in each shielded radio station compartment which are closed at ends by sound-conducting water-tight material and installed in pairs in bulkheads between compartments so that their butt-ends occur in adjacent compartments at distance multiple of , where N is integer number; lambda is working wavelength. EFFECT: enhanced reliability and survivability of shipboard emergency communications. 1 cl, 4 dwg
