Final answer:
To receive over-the-air local channels, installing a high-quality HD antenna is one option, allowing access to AM video and FM audio signals. Other methods include cable systems using coaxial or fiber optic cables, and satellite dishes that pick up orbiting signals.
Step-by-step explanation:
To receive local channels via over-the-air signals, one can install a high-quality HD antenna. Traditional roof antennas allow for the reception of these signals with the video component being broadcasted in AM and the audio in FM. An alternative way of receiving channels is through cable programming, which offers the ability to transmit signals to homes through coaxial or fiber optic cables without relying on airwaves and local affiliates. Satellite dishes receive TV signals sent from orbit, which can be detected by tuning the receiver to resonate at the specific frequency of these broadcasts, providing another means to access television content.
