When using a transmitter/receiver combination, how many antennas must be mounted on the UAS and on the GCS?

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

Answer: (B)

A basic transmitter/receiver setup needs an antenna on each end to establish the link between the ground control station and the unmanned aircraft. With a transmitter at the GCS and a receiver on the UAS, you mount one antenna on the UAS to receive the signal and one antenna on the GCS to transmit it. That equals two antennas in total. Some systems may add extra antennas for redundancy or diversity, but the minimum for a working link is one on each side.
