It then lay dormant until it was used very successfully to foil the German Y-Gerät radio navigation system during the last stages of the Battle of Britain.

After the war, it was reused for television until 1956, when it was superseded by the opening of the BBC's new main transmitting station for the London area at Crystal Palace.

In 1982 Alexandra Palace became an active transmitting station again, with the opening of a relay transmitter to provide UHF television service to parts of North London poorly covered from Crystal Palace.

As part of the 700 MHz clearance programme the UHF channel numbers were changed in March 2018.

BBC Two was closed on UHF 64 on 4 April 2012, when ITV1 temporarily moved into its frequency.
