An aircraft antenna installation must be grounded to what?

The nearest electrical system
The airframe
The engine block
A dedicated grounding rod

The correct answer is: The airframe

An aircraft antenna installation must be grounded to the airframe because the airframe acts as a conductive path for the electrical current. By grounding the antenna to the airframe, any static charges or electrical currents can safely dissipate through the airframe structure, reducing the risk of electrical interference or damage to the aircraft systems. Grounding the antenna to the nearest electrical system, the engine block, or a dedicated grounding rod would not provide the same level of protection and could potentially lead to electrical issues or damage to the aircraft.
