What is a RF modulator?

An RF modulator (Radio Frequency Modulator) is a device that converts audio and video signals into high-frequency RF signals. It is commonly used to transmit digital signals to older TVs or radios that lack the necessary input connections. The device modulates the input signal (e.g., AV signal) into an RF signal within a specific frequency range and outputs it through an antenna cable, allowing RF-compatible devices like TVs to receive and reproduce the signal. RF modulators are widely used in older analog TV setups and surveillance systems.
