Thule Air Base on Greenland. Globecom Tower, whose design is similar to that ofForestport Tower is a guyed lattice steel tower with triangular cross section (sidelength: 4.75 metres), which is anchored in 3 levels. It is designed as mast radiator insulated against ground and equipped with an elevator running up to a height of 360 metres.Globecom Tower was completed in 1954. It was at completion the tallest man-made structure outside USA and the third tallest in the world after KWTV Mast in Oklahoma City and
Empire State Building . A great difficulty at its construction was the fact, that the ground on which it was built is permanently frozen.Globecom Tower was used for transmitting military telex messages to Goose Bay, Canada on the longwave frequency 68.9 kHz with a power of 50 kW under the callsign XPH.
In 2003 these transmissions were terminated. Globecom Tower may still stand, but is today obviously unused.
