The Sender Feldberg/Black Forest (transmitter Black Forest) is a transmission facility for FM and TV on Feldberg, Black Forest, Germany. It has an old and a new transmission tower: The old transmission tower was built at (47°51′52″N8°01′20″E). It is a 75 metre high concrete tower with an observation deck in a height of 36 metres and a diameter of 9.1 metres, which is nowadays closed. This tower does not meet the radiotechnical requirements of our days, so it was replaced in 2003 by a new 82 metre tall transmission tower, which is as the old transmission tower built as a concrete tower.
