An Update on the Allen Telescope Array David R. DeBoer1 1 SETI Institute, 515 N. Whisman, Mountain View, CA 94043, USA, 1(510)643-2329 for smaller antennas. The Allen Telescope Array (ATA) is the first telescope to be designed with this in mind, and includes other innovations to enhance the performance per cost ratio. The Allen Telescope Array [1] is a joint project of the SETI Institute (Search
