TELEVISION AERIAL Meaning and
Definition
-
A television aerial, also referred to as a TV antenna or TV aerial, is an electronic device used to receive broadcast signals and allow the reception of television broadcasts. It is designed to capture television signals that are transmitted over the airwaves and convert them into electrical signals that can be processed by a television set.
The television aerial typically consists of a metal conductor or a series of conductors, such as rods or wires, arranged in a specific configuration to enhance signal reception. These conductors are generally made from materials like copper, aluminum, or steel to ensure efficient signal capture. The aerial is usually installed outdoors, mounted on a rooftop, pole, or other elevated structure, to optimize signal reception by avoiding obstructions such as buildings or trees.
Television aerials come in various types and designs, including the traditional Yagi, log-periodic, and dipole antennas. Each type has its own characteristics and suitability for different signal strengths and transmission frequencies.
The television aerial connects to a television set or a digital television receiver through a coaxial cable for signal transmission. It receives broadcast signals from local television stations, allowing viewers to access a wide range of channels and programs. With the advent of digital television, aerials have evolved to include features such as built-in signal amplification and filtering to enhance signal quality and improve reception.
