Cambridge Bay LORAN Tower was a tall free-standing lattice tower at Cambridge Bay, Nunavut, Canada. It was built in 1947/48 for LORAN transmissions. Later the tower was used as a non-directional beacon (NDB) and was often called the "CB" beacon after the morse code letters that it transmitted on 245 kHz, with an output power of 2000 watts. What appeared to be guy wires on the tower were 'top loading' forming part of the antenna. The tower was four sided and the base per side or . The tower was built around 1947 and became redundant with the construction of the Distant Early Warning Line in the 1950s.〔(Cold War casualty )〕〔(Cambridge Bay ) at the Canadian Encyclopedia〕 In 2013, the tower was determined to be structurally unsound and scheduled for demolition, to be replaced by a tower. The removal, which was supposed to have been completed in October 2013, was finally started in August 2014 and the tower taken down on the evening of 5 August.〔(Last call for tallest tower in western Nunavut )〕〔(Cambridge Bay, Nunavut Replacement of the ‘CB’ NDB )〕〔(Cambridge Bay residents bid farewell to a trusty old friend )〕 == See also ==
