Re: Do you know how i could build a dish that would recieve signals from space?

Greetings:

Your question refers to the science of Radio Astronomy and the equipment is
called a Radio Telescope. Today amateur radio astronomy is growing in popularity
and there are many sources of information to help amateurs build equipment.

A radio telescope can be broken down into four pieces of equipment:

1) An antenna with a narrow beam and large effective aperture to collect the very
weak signals coming from astronomical objects in space.

2) A low noise amplifier (LNA) located at the antenna to amplify the weak signals
collected by the antenna up to a level were they can be processed.

3) A down converter amplifier that changes the frequency of the signals and
amplifies them for listening, displaying and/or processing.

4) The output display, sound, or computer for recording, storing and processing
the signals.

These four pieces of equipment are very similar to the parabolic dish antennas
and microwave equipment now available for receiving direct broadcast satellite
(DBS) television from space. Many amateurs modify this equipment to operate as
a radio telescope. Links to information about radio telescopes can be found at

BAMBI is a project for amateur radio astronomers to share information on
the various equipment, kits, building plans, and circuit boards for amateurs
to build their own radio telescopes. BAMBI is a project in the Search for
Extra Terrestrial Intelligence (SETI) project. You will find a great amount of
information that you are seeking, including contacts in the United Kingdom,
