description A vertical receiver antenna (1) device is described, including first and second receiving electrode units (11a, 11b) interconnected by a receiver antenna cable (12) and connected to means (7, 8, 9, 23) for the electromagnetic surveying of electrically resistive targets (4) potentially containing hydrocarbons, the receiver antenna (1) being arranged in a tubular, non-magnetic antenna housing (2) arranged vertically in subsea uncompacted material (42), and one of the first and second receiving electrode units (11a, 11b) being connected in an electrically conductive manner to the underlying structure (42, 43), and the other one of the first and second receiving electrode units (11a, 11b) being arranged in a portion of the antenna housing (2) distantly from the first one of said first and second receiving electrode units (11a, 11b). There is also described a method of installing a vertical receiver antenna (1) in subsea uncompacted material (42). Se describe un dispositivo de antena receptora vertical (1), que incluye una primera unidad de electrodo receptor y una segunda unidad de electrodo receptor (11a,11b) interconectadas por un cable de antena receptora (12) y conectadas a medios (7, 8, 9, 23) para el estudio electromagnético de objetivos eléctricamente resistivos (4) que contienen potencialmente hidrocarburos, la antena receptora (1) está dispuesta en un alojamiento de antena no magnético tubular (2) dispuesto verticalmente en material submarino no compactado (42) y una de la primera unidad de electrodo receptor y la segunda unidad de electrodo receptor (11a, 11b) está conectada de manera eléctricamente conductiva a la estructura subyacente (42, 43) y la otra de la primera unidad de electrodo receptor y la segunda unidad de electrodo receptor (11a, 11b) está dispuesta en una porción del alojamiento de antena (2) a distancia de la primera unidad de electrodo receptor y la segunda unidad de electrodo receptor (11a, 11b) mencionada en principio. También se describe un método para instalar una antena receptora vertical (1) en el material submarino no compactado (42).
