High Quality Content by WIKIPEDIA articles! Sahlenburg Marine Radio Station was a facility of Elbe-Weser Radio in Sahlenburg, an urban part of Cuxhaven for marine radio service in short- and mediumwave range. Sahlenburg Marine Radio Station used first a triangular antenna, which was fixed on 3 guyed wooden masts, each 40 metres tall, which were erected in 1929. In 1937 these masts were replaced by three 50 metre tall free-standing wood towers with triangular cross sections, which also carried a triangular antenna. In 1967 two of these towers were dismantled and the other was equipped with a long wire antenna. In 1970 also this tower was demolished, after two 67 metre tall guyed insulated mast radiators, each 67 metres tall, were built. After the shut-down of Sahlenburg Marine Radio Station, they are used for mobile phone services.
