In 1924, masts were erected on a 50 acre site at Borough Hill, Daventry, for the first transmission of the BBC’s longwave radio service. A small steel ball placed between the mast base and a concrete block allowed the mast to flex with the wind, supporting a structure weighing 80 tonnes and standing 150 meters tall.
The site opened on 27 July 1925 and Daventry became the site of the world’s first long wave radio transmission station. The very first transmission from the station was of a poem called “Daventry Calling”.
The ceramic insulator ‘eggs’ helped hold together the increasing number of aerials needed for the shortwave radio service, which began in 1932. There were more than 40 long wave and shortwave masts and towers during the site’s golden age. The BBC’s Borough Hill station continued broadcasting until 1992, with the signal so strong that townsfolk could hear the World Service on everyday appliances like toasters and vacuum cleaners!
