Facts on Canada’s CN Tower

During Torontos building boom in the early 70s, a serious problem was developing. mickle were experiencing poor quality television. The pre-skyscraper contagious disease towers of Toronto stations were simply not high enough bothmore.As office buildings were orbit higher and higher, the video reply and radio signaq got weaker and soon became alomst inpossible to recieve. Signals from Toronto and from Buffalo, New York were bouncing off the buildings. As a result viewers often saw a weaker station superimposed over another. So the were honoring two shows at once. It became clear that they needed a antenna that would not only be taller than any building in the city, but one that would be taller than anything that would probably ever be make.Today, the microwave receivers which distill in distant signals are about 305 metres or 1000 feet up (inside that white donut-like thing), and the top of the transmission antenna is 553.33 metres or 1815 feet 5 inches high (thats the very to p).Because of this, we enjoy some of the clearest TV and radio reception in North America.
