Over-the-air television broadcast reception works by using radio waves to transmit the audio and video signals from the broadcasting station to the television's receiving antenna. Here are the basic steps for receiving TV broadcasts over the airwaves:
The television station sends the audio and video signal to a transmitting antenna which converts the signal into a radio wave.
The radio wave is then broadcast through the air from the transmitting antenna at a given frequency, usually in the UHF or VHF band.
Television receiving antennas pick up these radio waves from the air and transmit them inside the coaxial cable, which carries the audio and video signals to the television. The signals are then demodulated by the TV tuner, which separates the audio and video signals to process them separately.
The video signal is then displayed on the television screen, while the audio signal is sent to the speakers.
The quality of reception of over-the-air television broadcasts can vary depending on the reception quality of the receiving antenna, the quality of the equipment used, and the distance between the receiving antenna and the transmitting antenna. However, with a quality receiving antenna and the right equipment, receiving over-the-air television broadcasts can provide high-quality picture and sound quality.
