Summary
| Description |
English: Photograph of the 432 metre (1,417 ft) mast of the Station G transmitter at Woodside, Victoria, Australia of the former Omega navigation system, an obsolete worldwide navigation system that broadcast in the very low frequency band between 10 and 14 kHz. It was built in 1982 and demolished in 2015. This is an umbrella antenna consisting of a mast with diagonal topload wires attached to the top and stretching diagonally to the ground. This is a view of the top of the mast, showing the high voltage strain insulators supporting the ring of 16 topload wires. This umbrella-shaped topload formed a capacitor plate, increasing the current in the mast to increase the radiated power. |
