From Wikipedia, the free encyclopedia

The VLF transmitter Criggion was a VLF transmitter for 19.6 kHz located near the village of Criggion in the Bauseley with Criggion community, which lies in the principal area of Powys, Wales. It was established in World War II as backup unit for the Rugby VLF transmitter. It was used until its shutdown on April 1, 2003 for transmitting orders to submarines. Its task is now done by the Anthorn VLF transmitter. The aerial of VLF Transmitter Criggion was a wire aerial hung up on three freestanding steel framework towers (height 182.9 metres), two guyed masts (height: 213.4 metres) and a rock anchor. The towers and masts were demolished in August 2003.
