Explanation: Proper grounding for an Inmarsat-C terminal on a ship requires both excellent electrical conductivity for RF signals and robust corrosion prevention. A copper strap is superior to a round wire for RF grounding because its wider surface area results in lower inductance, providing a more effective path for high-frequency currents. Brazing creates a permanent, low-resistance metallurgical bond between the copper strap and the steel hull/terminal. This critical step ensures excellent electrical continuity and, importantly, prevents galvanic corrosion, which is a major concern in marine environments where dissimilar metals (like aluminum and steel, or even poorly connected copper to steel) can rapidly corrode when exposed to an electrolyte like seawater. Simply using a wire (A) provides higher inductance. Relying only on antenna grounding (B) is insufficient, as the terminal itself requires proper grounding for safety and RF integrity. Using an aluminum strap bolted to steel (D) would lead to severe galvanic corrosion, compromising the electrical connection and structural integrity over time.
