DISH ANTENNA
| A dish antenna is short for the expression "parabolic dish antenna".
Such an antenna is highly directional
and will concentrate receive or transmitter energy in a singular beamed
direction. Dish antennas are mostly used for
point-to-point
communications - meaning reception or transmission in one direction
only. One of the most common usages of dish antennas is for
satellite transmission and reception. For satellites of course,
the direction is a very definite single direction and the distance very
far away, so for both reasons, it makes sense to use a dish antenna. |
