12 Dec 2018 Searches for Extraterrestrial Intelligence (SETI) at radio frequencies Using measured antenna system temperatures, Table 1 displays the 

the total address space of this SETI station is then: Addr = F * DEC * Ra where. F = 20 KHz. Each capture of the water hole for analysis is 20 KHz wide. F= 100E6/20E3 or ~ 5,000 places. DEC = (+/- 90 Deg) / HPBW. The Half Power Beam Width of the antenna is 3.8 degrees at 1420 MHz. DEC = 180/3.8 or ~ 47 places

The Allen Telescope Array ( ATA ), formerly known as the One Hectare Telescope ( 1hT ), is a radio telescope array dedicated to astronomical observations and a simultaneous search for extraterrestrial intelligence (SETI). The array is situated at the Hat Creek Radio Observatory in Shasta County, 290 miles (470 km) northeast of San Francisco, California. Song of SETI . Antenna. Set Up Antenna (32 bit stand alone application). The SETI Net home station antenna (DM12jw) consists of a 10 foot dish and twin rotors each with 180° of movement.

One of Tony's antennas, used for 2.4 GHz satellite reception, is shown in Figure 9, and was an inspiration for the SETI Horn of Plenty. Unfortunately, cardboard and foil proved insufficiently robust for our purposes, and we had to resort to 26 gauge galvanized sheet steel.

The SETI Net home station antenna (DM12jw) consists of a 10 foot dish and twin rotors each with 180° of movement. The rotors are stacked, using a specially built adapter so that combined they can position the antenna nearly any where in a 360°of azimuth and 90° elevation. The Arecibo Observatory, also known as the National Astronomy and Ionosphere Center (NAIC) and formerly known as the Arecibo Ionosphere Observatory, is an observatory in Barrio Esperanza, Arecibo, Puerto Rico owned by the US National Science Foundation (NSF).. The observatory's main instrument was the Arecibo Telescope, a 305 m (1,000 ft) spherical reflector dish built into a natural sinkhole 2020-11-20 The Search for Extraterrestrial Intelligence (SETI) is conducted by dedicated scientists everyday.

Although numerous antenna options exist for amateur SETI stations, by far the most popular approach is to use a three- to five-meter (ten- to sixteen-foot) satellite TV dish, with a prime-focus feedhorn appropriate to the radioastronomy frequencies. Many SETI League members already possess suitable dishes, either currently or formerly used by them with Television Recieve Only (TVRO) systems. Soviet scientists took a strong interest in SETI during the 1960s and performed a number of searches with omnidirectional antennas in the hope of picking up powerful radio signals.
