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 telescope consists of an 18 inch directv satellite dish with low noise block (LNB), a satellite finder and an RTL-SDR dongle connected to a laptop. 2. It is used by default for the LOFAR radio telescope and thus is in productional stage. Another fun radio astronomy project is to use an SDR (the funcube-dongle Pro+ might be more suitable here due to higher dynamic range) and a dipole or small Yagi to record meteor reflections. As such is it a fair amount more difficult to learn and use compared to SDR# and HDSDR. Basically I want something that I can put together, more or less out of the box, and listen to the Hydrogen band with. The radio window that allows in radio frequencies through the Earth's atmosphere have wavelengths between about 0.5 cm to about 30 m. If I got this right, a quarter wavelength receiver would need to be about 7.5 m in length. SDR-RADIO.COM V2/V3 (Windows) (Free) SDR-RADIO.COM V2.
