Alexandra Palace Transmitter

Encyclopedia : A : AL : ALE : Alexandra Palace Transmitter

The transmission mast above the BBC wing of Alexandra Palace, photographed in 2001.

The Alexandra Palace transmitter (Grid reference ) is one of the oldest television transmission sites in the world; high definition (405-line) VHF broadcasts took place from this mast between 1936 (with a break for WWII) and 1956 when it was superseded by the opening of the BBC's new main transmitting station for the London area at Crystal Palace.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 which are unable to directly receive broadcasts from Crystal Palace.

The transmitter is owned and maintained by National Grid Wireless.
