The array will consist of commercial satellite dishes fitted with sensitive but inexpensive, purpose-built receivers, enabling a high-performance instrument to be constructed at a fraction of the cost of a single large dish and receiver. The useful frequency range will be from under 1 GHz to between 10 and 25 GHz. When completed, the ATA, named for Microsoft Corp. co-founder Paul Allen, who donated some of the $12.5 million construction costs, will be the world's largest observatory facility devoted substantially to the search for intelligent signals from space. It will be located alongside the Hat Creek Observatory of the University of California, Berkeley, near Mount Lassen in northern California. The first 42 telescopes of the ATA are scheduled began making observations around the clock in October 2007.
