Naval Radio Transmitter Facility Grindavik

Naval Radio Transmitter Facility Grindavik (NRTF Grindavik) is a transmission facility of the US Navy at Grindavík, Iceland, maintained by the N62 Division. It is active on shortwave and longwave under the callsign TFK on 37.6 kHz.

NRTF Grindavik originally had two towers for its longwave service – the west tower with a height of 243.8 metres (800 ft) and the east tower with a height of 182.9 metres (600 ft) – which were, when built, the tallest man-made objects in Iceland. In 1983, the east tower was replaced by a new tower of the same height. The west tower was replaced by a new 304.8-metre (1,000 ft) guyed mast and 2,500-square-foot (230 m2) helix house, now the second tallest structure in Iceland.

NRTF Grindavik was the 1999 winner of the Defense Information Systems Agency (DISA) Outstanding Transmission Facility Award (Category II), and was a runner up in the same category in 1997. The new taller antenna and helix house were structurally designed by Donald W. Anderson, PE[1] who additionally managed the design and construction programs while employed at Naval Facilities Engineering Command (NAVFAC), Atlantic. The final design incorporated many new and improved items which required integrated electronic and structural designs, including a new and improved helix house RF copper shielding design and installation method. All successes in the program improved on former designs and were partially influential in the previously-mentioned awards.

The N62 Division is divided into three subdivision: N62A, Antenna Maintenance; N62B, longwave equipment and ISABPS Maintenance; and N62C, shortwave equipment and Ancillary Equipment Maintenance.
