Emergency Telecommunicator Certification Practice Exam

Is a transmitter antenna required to receive radio signals?

1. True

2. False

3. Only in high-frequency transmission

4. Only in two-way communication

The correct answer is: False

A transmitter antenna is not required to receive radio signals because receiving radio signals typically involves a receiver antenna. A transmitter antenna is essential for sending out signals, but the receiving process specifically relies on a receiver that can interpret the signals broadcast by a transmitter. In the context of radio communication, the receiving antenna captures incoming radio waves, which are then processed by the receiver to extract the information being transmitted. This function is distinct from that of a transmitter antenna, which is designed to generate and radiate signals into the air. The premise of the question revolves around the fundamental operation of radio communications. A receiver can effectively pick up signals without necessitating the presence of a transmitter antenna, as long as there is a properly functioning receiver with its own antenna.
