Which item is not typically listed as part of a field expedient antenna?

• A. Powered transmitter
• B. Radiating element (wire)
• C. Insulators
• D. A support structure

Answer: (A)

The main idea here is distinguishing what actually constitutes the antenna hardware from the energy source that drives it. A field expedient antenna is built from components that form the radiating structure: the radiating element (wire) which creates the electromagnetic field, insulators that keep the element properly isolated and positioned, and a support structure that holds everything in the right place and orientation. The powered transmitter, while essential to a radio link, is a separate device that generates and feeds RF energy into the antenna via a feedline. It isn’t part of the antenna itself, so it isn’t listed as a field expedient antenna component.
