505:, University College, London. The original twenty mast circular aerial was destroyed in a storm on 17 September 1901. Marconi hastily built a temporary aerial of 50 wires suspended in a fan shape from a cable between two 200 foot (61 m) masts. Fleming estimated the transmitter's radiated power was around 10–12 kW. The frequency used is not known precisely, as Marconi did not measure wavelength or frequency, but it was between 166 and 984 kHz, probably around 500 kHz. After the experiment the original mast layout was not rebuilt, it was replaced with a four mast design, 215 feet (66 m) high and forming a 200-foot (61 m) square. 48: 509: 457: 907: 55: 227: 480:. The station was built partly on cliff top pastures that had been enclosed in 1871 and partly on medieval fields belonging to a nearby settlement, Angrouse. The fifty acre (200,000 m) plot was bought in 1900 and building work ran from October 1900 to January 1901. During the work two 565: 556: 267: 1137: 630:
