The LORAN-C transmitter Jan Mayen is a LORAN-C transmission facility on the island of Jan Mayen at 70°54′51″N 8°43′57″W. The LORAN-C transmitter Jan Mayen uses as antenna a 190-metre high (625 ft) guyed mast.
This mast was built as replacement of a 190.5 metre tall mast, which collapsed in a storm on 8 October 1980 as the result of too low tension on the guy wires. The guywires were adjusted by personnel from the USCG who mixed up pounds and kilograms.
Both transmitters on Jan Mayen (Bø and Edje), together with all other Norwegian LORAN-C transmitters, was shut off at midnight on Dec 31, 2015
