DISH ANTENNA Meaning and
Definition
-
A dish antenna, also known as a satellite dish or parabolic reflector, is a specialized type of antenna designed to receive or transmit signals from or to satellites in space. It consists of a concave-shaped metal reflector, commonly made of aluminum, and is characterized by a dish-like appearance, hence the name.
The dish antenna works on the principle of reflection, where it reflects and focuses incoming electromagnetic waves onto the feedhorn or LNB (Low Noise Block) at its focal point. This enables the antenna to capture or emit signals with high precision and efficiency. The dish's shape allows it to concentrate the incoming waves to a single point, enhancing its performance and signal reception capabilities.
Dish antennas are commonly used in satellite communication systems for both residential and commercial applications. They play a vital role in receiving television signals from satellites, allowing viewers to access a wide range of channels and programming. Additionally, dish antennas are utilized in various other industries, such as telecommunications, meteorology, and military applications.
The size of a dish antenna can vary, ranging from small dishes used for individual homes to larger ones used in commercial installations. The size of the dish is determined by the desired signal strength, frequency range, and geographical location. The larger the dish, the greater its gain and ability to capture weak signals.
Overall, dish antennas are fundamental in establishing reliable and efficient communication links with satellites, enabling seamless transmission of data, audio, and video signals over vast distances.

Etymology of DISH ANTENNA
The term "dish antenna" derives from the Latin word "discus", which means a disk or a flat, circular object. In the context of antennas, the term was coined due to the shape of the device resembling a dish or plate. This type of antenna is commonly referred to as a parabolic reflector, as it consists of a concave dish-shaped surface that reflects and focuses radio waves onto a receiver located at the focal point. Over time, the term "dish antenna" became widely used to describe this specific type of antenna configuration.
