Formerly known as KTHI – TV is currently the 3rd tallest man made structure on earth standing up to a height of 628.8 m. above the ground level. It is being used as a TV transmission (VHF/UHF transmission) tower which is located 3 miles to the west of Blanchard, north Dakota  halfway between Fargo and Grand Forks. Dallas based  Hoak Media corporation is owning this artificial tall structure which is one of the 18 towers it is owning currently.

The tower was built by Hamilton Electric Company York, South Carolina and Kline iron and steel, and took thirty days to complete, at a cost of US$ 500,000 to break the record of  Warszawa radio mast  in Poland, which collapsed on August 8, 1991. The KVLY tower broadcasts at 365 kW for television station KVLY TV (channel 11 PSIP, an NBC affiliate) which is based in Fargo. The tower provides a broadcast area of roughly 78,000 km2 which is a radius of about 156 km. Its height above the mean sea level is 926 m. This tower is an architecture of Hamilton directors and was completed on 13th August 1963. The main contractor was Kline iron and Steel. The tower contains 2 million feets of steel, guy wire strands and elevator cable. The tower and guy anchors take up 160 acres of space. The antenna on top of the tower is 113 feet high and weighs 9,000 pounds. The steel tower is taller than the combined height of the Great Pyramid Khufu at Giza, the Eiffel Tower in Paris and the Washington Monument. If the KVLY tower had its base at the bottom of the Royal Gorge in Colorado, the antenna would still be 563 feet above the upper rim. If a 20 second commercial started at the same moment a baseball was dropped from the top of the KVLY tower, it would end nearly four seconds before the ball hit the ground. In a 70 mile-per-hour wind, the beacon light on top of the KVLY tower will move approximately ten feet. If an iron worker on the antenna dropped his wrench, it would be traveling at a speed of 250 miles per hour when it hit the ground. If a hunter at the base of the KVLY tower shot at a goose flying near the top with a .45 caliber pistol, he would have to lead the goose by more than the length of a football field, or approximately 335 feet. The tower was assembled in 33 working days by an 11-man crew with no casualties. The total weight of steel in the tower is 864,500 pounds. The total length of guy wires is 40,125 feet, or 7.6 miles. The elevator cable used in construction of the tower is 7,870 feet.
