What part or components of the radio tuner intercepts and coLLects signal?

The part of a radio tuner that intercepts and collects signals is called the antenna. The antenna is designed to capture electromagnetic waves, which carry the radio signals, and convert them into electrical signals that can be processed by the tuner. Antennas come in various types, including dipole antennas, loop antennas, and dish antennas, each with its own characteristics and suitability for different frequency ranges. The antenna is a crucial component of a radio tuner as it determines the quality and strength of the signals received and processed by the tuner's subsequent stages.
