The KXJB-TV mast is a television transmitting tower in Traill County, North Dakotamarker, United Statesmarker. At 2060 ft (628 m), it is the third-tallest artificial structure in the world, shorter by 3 ft (1 m) than the KVLY-TV mastmarker which stands a few miles away.

Located 3.5 miles (6 km) northeast of Galesburg, North Dakotamarker, it was completed in 1966, to replace the station's previous mast, a 1,085-foot (331 m) tower 15 miles (25 km) northeast of Valley City, North Dakotamarker which was sold to KOVCmarker, an AM radio station.

The antenna transmits at 100 kW for CBS affiliate KXJBmarker of Valley City/Fargo; the station and tower are owned by Parker Broadcasting of Fargomarker.

Collapses

The mast has fallen and been rebuilt twice. The first collapse occurred at 9:08 A.M. February 14, 1968 when the rotor of a Marine helicopter severed some guy wires (all four aboard the helicopter were killed in the mishap). The television station was off the air for eight days, finally resuming broadcasts from their previous (KOVC) tower. A replacement mast of the same height as the one destroyed was completed in four and a half months.

The second mast fell during an ice storm which hit the area on April 6, 1997, subjecting it to wind gusts of 70mph and causing at least four inches (100 mm) of ice to accumulate on the structure, resulting in the structure's failure at 6:09 P.M.. Cable programming was resumed by 8:34 and broadcasts by 3 P.M. the following afternoon through coordination with other affiliates; a 735-foot (224 m) temporary tower was completed and resumed broadcasts by July 10. This tower still stands next to the full-height mast.

Work began on replacement of the full-height mast with a more durably-built structure on April 1, 1998, and had reached the tower's previous height by July 30. That day members of the construction crew affixed a four-foot (1.2 m) flagpole to the top of the tower, making the structure's height effectively 2064 ft (629 m), or one foot higher than the KVLY mast (the flagpole was later removed). Broadcasting for Channel 4 was switched to the new mast on August 15.

KXJB-TV Mast 2

Close to KXJB-TV mast, there is a second guyed mast with a height of 224 metres.
