The Cape Race LORAN-C transmitter was used as an antenna tower until February 2, 1993. It was a 411.48 m (1350 ft) tall guyed mast, built in 1965. This mast was the tallest structure in Canada until the construction of the CN Tower in Toronto, and remained the second-tallest structure until its collapse on February 2, 1993. The collapse was the result of a fatigue failure of the eyebolt head in a compression cone insulator on a structural guy-wire. This failure caused swing-in damage that resulted in the tower's collapse. The tower was replaced by a 260.3 meter (854 ft) tall guyed mast, insulated against the ground.

The Cape Race LORAN-C transmitter was used until 1993 as part of the LORAN-C Chain GRI 9930 and worked with a transmission power of 1800 kilowatts. Today the Cape Race LORAN-C transmitter acts as the Yankee Secondary Transmitter of the Canadian East Coast LORAN-C chain (GRI 5930) and as the Whiskey Secondary of the Newfoundland East Coast LORAN-C chain (GRI 7270).

The transmission power for the Canadian East Coast LORAN-C chain is 1000 kW, and for the Newfoundland East Coast LORAN-C the transmission power is 500 kW.
