PARABOLIC ANTENNA
| A Parabolic Antenna may also be called a
dish antenna. The parabolic shape is of course similar to a
dish in appearance. The purpose of a parabolic antenna is to
concentrate the energy coming into the antenna from a single direction
to a high energy reception point. For receive, visualize the
energy coming into the sides of the dish, and then reflecting to a
central receiving element. |

Parabolic or dish antennas therefore concentrate antenna energy that
is arriving or being sent in a very singular direction.
Therefore with this concentration of antenna energy, the antennas are
said to be high gain and will be able to
receive signals long distances - even from satellites - as long as the
dish antenna is pointed in precisely the right direction for the signal
to be sent or received.
