Q

What is the best method for grounding an Inmarsat-C terminal?

🔍 Key Concepts

• Grounding and bonding principles for radio and GMDSS equipment on steel ships • Differences between wire vs. strap as a grounding conductor (surface area, impedance to RF currents) • Material compatibility and corrosion issues when joining different metals on a steel hull

💭 Think About

• Think about which option will provide the lowest impedance path for RF and lightning energy from the terminal to the ship’s hull. • Consider why a wide, flat conductor might be preferred over a small round wire for high‑frequency and impulse currents. • Ask yourself which metal in the answers is most compatible with a steel hull and least likely to cause corrosion or poor contact over time.

✅ Before You Answer

• Verify which option uses a wide copper strap rather than a small round wire. • Check for any answer that avoids dissimilar metals (like aluminum to steel) that could corrode at the joints. • Confirm that the bonding method described makes a solid, permanent, low‑resistance connection directly between terminal and hull.
