Because the shape of the dish focuses the incoming weak radio waves to a point - which serves to amplify them, and the increased signal is then sent down the feed cable to the receiver.

What is meant by parabolic?
It means in the shape of a parabola.
What would be a good shape for a thermal solar panel?
parabolic convex
Why you are using parabolic shape for radio telescope?
A parabolic shape is used for all reflecting collectors ... visible light telescope, radio telescope, satellite receiver, etc. A parabolic reflector directs all parallel incoming rays toward one point, called the 'focus' of the parabola.
Will an object display a parabolic shape if thrown form the Moon's surface?
Yes
What uses are there for parabolic mirrors?
Parabolic mirrors are formed in a dish like shape, the purpose of it's shape is to transmit the electromagnet waves. For example when using a microwave or watching a television, it is through electromagnet radiation that make it possible to function. Television receives the signals via the satellite dish, the satellite dish acts as the parabolic mirror.
What are the Bending moment diagram for simply supported beam with udl?
Parabolic, max moment at midspan of value wL^2/8 where w is the distributed load and L the length of the beam.
Why the parabolic antenna has parabola shape?
Parallel rays, such as those from a very distance source, are focussed by a parabolic antenna so that they all meet at the focus of the parabola. This results in a stronger signal.
What shape is the mirror used to reflect TV waves from a satellite?
Probably parabolic (not 100% on that thou)
How do you build a parabolic mirror?
A parabolic mirror is shaped such that parallel incident light is reflected to a point called the focus. You will have to establish the size required, and the shape. There is an entry in Wikipedia on Parabola, giving the algebra.
Projectile following a parabolic path on a circle?
A projectile doesn't follow a circular path. It follows a parabolic path. No part of a circle has the same shape as any part of a parabola. They're different curves.
How do dogs' ears shapes help them hear?
The shape acts like a parabolic antenna, focusing sound into the ear from a larger surface area. Simples.
