In a simple field expedient antenna, which item serves as the radiating element?

• A. Radiating element (wire)
• B. Insulators
• C. A support structure
• D. Ground stake

Answer: (A)

The key idea is that the part actually emitting and receiving the RF energy is the conductor that carries the current. In a simple field expedient antenna, that conductor is the wire itself, which acts as the radiator. The insulators just keep the wire from shorting or touching other parts, the support structure only holds things up, and the ground stake provides anchoring—their roles are mechanical or insulating, not radiating. So the wire is the radiating element.
