... Astrophysics Group . ... MRAO Telescopes . ... A radio telescope consists of one or more directional receiving aerials connected to very sensitive amplifiers. Since radio wavelengths range from millimetres to about 10 metres, the actual form of the aerials can vary greatly; many are parabolic dishes with very precise surfaces, while others, like the Cambridge Low-Frequency Synthesis Telescope (right), are similar to television aerials. ...
