The radio transmitter at Mangersta was a slave station in the North-East Atlantic Loran-A chain, which provided voice radio coverage to civil and military aircraft west of the Outer Hebrides. The master station in the chain was on the Faroe Islands. The Loran-A chains were gradually replaced by the Loran-C system, with the station at Mangersta closed by 1985.
