  1. May be you already know about this site. Just in case... I find it very interesting: http://www.discovercircuits.com/list.htm
  2. Hello there! I have found many interesting sites over the internet related to radioastronomy. In some of them it is explained that extraterrestrial signals may be rated from a few Mhz up to several Ghz. In commercial websites I've seen that common tv parabolic antennas have certain bandwidth. Most of them point to 12 Ghz. I am aware of antenna and parabola are two different things. The latest is just to focus the signal, while the antenna itself is the one with reception duties. On the other hand, as can be seen on http://www.turnpoint.net/wireless/cantennahowto.html , building a 2.4 Ghz antenna is extremely easy. I am not radio skilled, so I would like to get information about how to build a larger bandwidth antenna so I can get several reception ranges. That would lead to get further information about star temperatures, and other interesting information. I guess that it can be reached, since radioastronomy stations are able to get wide information. I would be so thankfully If you let me know about websites related to antenna building and theory.
