To start with, a very short history of radio astronomy would be helpful. Radio astronomy was born in the early 1930s when Karl Jansky, working for Bell Laboratories, was trying to determine the origin of a source of noise that was showing up in receivers operating in the 20 MHz region of the radio spectrum.
The radio telescope is used to detect most of the things that an optical telescope can not see. The comments of a radio telescope are the same as in a car radio. The both have the antenna, the receiver, the detector, and the computer or speaker. The radio telescope's dish has to be very large. The reason for this is that the radio telescope detects very weak signals. So it has to be big to do that. The dish of a radio telescope collects all the waves at the wave length that the receiver is tuned to.
