Marinefunksendestelle Hürup, Naval radio transmitter facility in Hürup, Germany.

Marinefunksendestelle Hürup was a German Navy coastal radio station for shortwave in Hürup near Husbyfeld. It began in November 1981 as a longwave transmitter using an antenna suspended from three grounded steel lattice masts, each 160 metres tall. The longwave service ended in 2002 and the masts were demolished by controlled demolition on 17 November 2004; a shortwave station was then built on the site.

The site began operating in November 1981 as a longwave naval transmitter, with its antenna suspended from three grounded steel lattice masts each 160 metres tall. Longwave operations ceased in 2002, and the masts were demolished by controlled explosion on 17 November 2004. A shortwave coastal radio station was then built on the area, and military use ended in 2015.

The site's name refers to Hürup, where the naval radio station operated in the mobile maritime radio service. The longwave transmitter went into service in November 1981, and after longwave operations ended in 2002 the three 160-metre masts were demolished on 17 November 2004. A shortwave coastal radio station was then built on the area, and military use ended in 2015.

The site lies near Husbyfeld in the Schleswig-Flensburg district. The three 160-metre masts were demolished on 17 November 2004, so nothing of the antenna array remains; what stands today belongs to the renewable energy park built after military use ended in 2015. The grounds are not open to visitors, but the site can be seen from public paths around the perimeter.

The three masts required specialized grounding techniques to support stable antenna systems across their entire 160-meter height. This technical challenge made them examples of advanced German engineering from the 1980s.
