What is cable aerial?

A cable aerial, also known as a cable antenna or a coaxial cable antenna, is a type of antenna that uses a coaxial cable to transmit and receive radio frequency signals. It is commonly used for TV reception and cable internet access.

The cable aerial is composed of a coaxial cable that is connected to a device called a balun. The balun converts the electrical signal that travels through the coaxial cable into a radio frequency signal that can be received by a TV or other type of radio equipment. The cable aerial is usually mounted outside a building, either attached to a mast or anchored to a wall.

One advantage of using a cable aerial is that it can provide a stronger and more stable signal than other types of antennas, such as a simple metal rod or a rabbit-ears antenna. Additionally, cable aerials can receive signals from a wide range of frequencies, making them versatile and compatible with many types of radio equipment. However, they may require professional installation and maintenance, and can be affected by weather conditions, such as high winds or lightning strikes.
