TV channel 17 (488-494 MHz) Collapsed Easter Sunday. WAND and WJJY used the same RCA UHF antennas, mfg in 1969. Upper section of antenna broke loose and destroyed guy wires due to ice storm This tower was one of the three tallest structures in the Northern Hemisphere and its transmitter radiated the most powerful UHF-TV signal in the world. Speculation of 'galloping guy lines' (mechanical standing waves in one of the guys), causing stress-to-failure in the guys due to rapidly alternating strain.Ģ4 two-inch coupling bolts connecting the second and third sections of the tower snapped due to ice formation No definitive cause ever found for collapse. RCA contractor for erection, stainless subcontractor. Had elevator, RCA Travelling Wave pylon antenna for Channel 12 (System M), land mobile antennas, all lost.

Masts and towers can collapse as a result of natural disasters, such as storms and fires from engineering defects and from accidents, sabotage and bendover. This is a list of catastrophic collapses of broadcast masts and towers.
