Lagrange Points L4 and L5 The Lagrange points are a special search area watched closley by SETI Net. This approach skews the antenna pattern slightly, but the result is easily measured by peaking the antenna on sun noise, and compensating aiming accordingly. Such a dual feedhorn design is a viable alternative for those members wishing to use a single dish simultaneously for satellite TV reception and SETI. 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 radio telescopes are basically souped-up antennas, SETI’s ATA collects between 500 and 10,000 megahertz (MHz). You'll Love This A Look at the Epic 50-Year Search for E.T. The instrument was operated and maintained by RAL until development of the array was put on hold in 2011. RAL worked hand in hand with the SETI Institute during design and prototyping and was the primary designer of the feed, antenna surfaces, beamforming, correlator, and imaging system for radio astronomy observations.

Parabolic Reflector (Dish) Antennas for SETI. 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.

The SETI antenna is pointing due East but the target is below the horizon. The target rises and its beacon is detected. What frequency is that beacon being transmitted on? We are not exactly sure, but we do know that because of the rotation of the Earth it appears to us to be higher than it actually is.
