What Is RF On My TV And How Does It Work?
RF, or Radio Frequency, is a feature on your TV that allows it to receive broadcast signals from the airwaves. It works by using an antenna or cable connection to capture the signals, which are then decoded and displayed on your TV screen. This feature is commonly used for watching over-the-air channels, such as local news and sports.
The RF signal is transmitted from a broadcast tower and received by your TV’s tuner, which is usually built into the TV or a separate device such as a digital converter box. The tuner decodes the signal and extracts the video and audio information, which is then displayed on your TV screen. RF signals can be affected by various factors, such as distance from the broadcast tower, terrain, and interference from other devices.
How Do I Set Up RF On My TV?
To set up RF on your TV, you will need to connect an antenna or cable to the RF input on your TV.
