Antennas which are related to the parabolic reflectors are the most common type of directive antennas when we require the higher amount of gain.
When we talk about the pointing a satellite dish, the two primary considerations are the angle of azimuth and elevation.
Here angle of elevation is the angle where our satellite dish is pointed into the sky at a (typically 90°) angle to the signal from the satellite.
When we have 0° angle of elevation then it is considered parallel with the earth and when we have 90° angle of elevation it is considered as pointing straight up into the sky.
Some antenna systems provide azimuth rotation which is a rotation about a vertical axis. Antenna positioning systems often provide both azimuth and elevation or the vertical and horizontal rotation of the antenna. The dish antenna should always point to a satellite in space to receive maximum signal.
