Antina is a metaldish fixed in a stand. It is the biggest part of this and it can be rotated to any direction towards sky.

The signals coming from far distance recieved by the Antina will be extremelyweak. These weak signals are magnified by radio reciever and send into a loudspeaker thereby astrophysists and scientist can identify the singnals and can be markedin charts.
