1. How do TV aerials work ?

TV antennas, also known as TV aerials or TV antennas, work by receiving television signals that are broadcasted over the airwaves. These signals are transmitted by TV stations and contain audio and video information. TV antennas capture these signals and convert them into electrical signals, which are then sent to the TV for decoding and displaying the television content.

TV antennas consist of a metal rod or an array of metal elements that are designed to resonate with the frequency of the TV signals. When the TV signals pass through the antenna, they induce a small electrical current in the antenna elements. This current is then amplified and sent to the TV through a coaxial cable, where it is processed and displayed as a television program.

It's important to note that TV antennas are specific to the type of TV signal being broadcasted in a particular area. For example, in regions where digital TV signals are used (such as DVB-T or ATSC), antennas are designed to receive and process these digital signals. The type and design of the antenna depend on factors such as signal strength, distance to TV transmitters, and local terrain.

2. How can you watch TV without an aerial?
