Which of the following is a correct statement about a satellite television antenna?

A satellite television antenna is specifically designed to receive signals from satellites orbiting the Earth. For optimal performance, an unobstructed line of sight to the satellite is essential. This means that there should be no physical barriers, such as buildings, trees, or mountains, blocking the antenna’s view of the sky where the satellite is positioned. If the line of sight is obstructed, the signal may be weak or completely lost, resulting in poor picture quality or no reception at all.

The requirement for a clear view is critical due to the nature of how satellite signals travel; they are transmitted in a straight line from the satellite to the antenna. This makes it necessary for the satellite dish to be meticulously aimed towards the satellite’s location in the sky to receive the transmitted signals effectively.

In contrast, other options describe inaccuracies regarding the functionality and requirements of satellite antennas, such as the misunderstandings about obstructions, power needs, and orientation.
