Vigra transmitter
From Wikipedia, the free encyclopedia
Vigra transmitter is a facility for medium wave broadcasting near Vigra in Norway. The Vigra transmitter was inaugurated in 1934. It was used until 1953 for transmission as a T-antenna. This antenna was replaced in 1952/53 by a guyed, steel-tube mast radiator insulated against the earth with a height of 243 metres. In 1999, the height of the mast was reduced for air traffic safety reasons to 232 metres.
The Vigra transmitter frequency is 630 kHz with a power of 100 kilowatts, which can be received at night in much of Europe.
