A simple 11.2 GHz RadioTelescope (HW part)
Abstract : In this post we describe the construction of a small amateur radio telescope operating at the frequency of 11.2 GHz. The construction of the radio telescope takes advantage of the satellite TV market which has made it easy and cheap to find parabolic reflector antennas with relative illuminator (feed horn) and LNB block (low noise amplifier-frequency converter). The performances of a similar instrument are naturally rather limited, however they still allow to make interesting observations of some of the most intense radio sources. Introduction Radio astronomy is a difficult and fas...
