They are used to explore new environments.
The purpose of an antenna on a radio or tv set is so that it can get signal so we can view tv or listen to the radio
A satellite antenna has one very important purpose. It is designed to allow a home to receive a satellite signal, which then allows users to receive a television signal.
An insects antenna serves the purpose of sensing things such as sound, heat and touch, among others. Antennas in telecommunications are used to intercept signals from over the air wavelengths.
The parallel-tuned filter in antenna circuit rejects only the undesired frequencies.
Spiders with antenna use them to sense their surroundings, helping them navigate, find food, and detect potential threats.
The main purpose of the Earth station antenna is that it receives and RF signal, which it turns into an electromagnetic wave and sends to a satellite. It then transfers the energy from the satellite to different signals and sends it to receiving equipment.
Antenna balls are generally used for decorative purposes, like a "smiley-face" antenna ball. They can also be used for advertising purposes, when containing a business or company logo.
Antenna balls are purely decorative items. However, they can be branded to serve as advertising, and some people ensure their antenna ball is distinctive to make it easier to find their car in a large parking lot.
A; it is to match the cable line impedance to the receiver for maximum transfer of energy
