In a transmitter/receiver pairing, how many antennas are required on the UAS and GCS?

• A. Four
• B. Two
• C. One
• D. Three

Answer: (B)

Communication between a transmitter and a receiver requires an antenna on each end. In a UAS–GCS pairing, commands travel from the GCS to the UAS and telemetry or responses travel back from the UAS to the GCS. Having one antenna on the UAS and one on the GCS provides the basic two-way link. Additional antennas can improve reliability or data rate, but they’re not required for the basic pairing. So the necessary setup is two antennas total—one on each side.
