🔍 Key Concepts

• Inmarsat-C fault indications and what an "Antenna not connected" alarm is actually monitoring • Basic coaxial cable continuity (open circuit vs short circuit vs normal low resistance) • Logical troubleshooting sequence: simplest, most direct cause that matches the specific alarm

💭 Think About

• Ask yourself: does changing satellites or software settings fix a physical problem that says the antenna is not connected? • Which options describe a realistic continuity test on a coax cable, and do the numbers given make sense for a short length of coax? • Between replacing circuit boards and the whole antenna, which action most directly addresses an alarm that the terminal cannot "see" the antenna electrically?

✅ Before You Answer

• Verify what an "Antenna not connected" alarm usually means (open circuit between terminal and antenna, or no DC power draw). • Think about what resistance value you would expect when you deliberately short the far end of a coax and measure at the near end (very low, or above one ohm?). • Check which option best matches standard, safe troubleshooting practice for an Inmarsat-C terminal when it reports the antenna is not connected.
