What is the antenna requirement aboard a survival craft equipped with a non-portable radiotelegraph installation?

🔍 Key Concepts

• SOLAS survival craft radio requirements for lifeboats and life rafts • Differences between portable vs. non‑portable radiotelegraph installations • Physical/structural limits on antennas with respect to height and length above the waterline on small craft

💭 Think About

• Look at each option and ask: which one sounds like a very specific regulatory wording for survival craft, and which sound like general radio/antenna practice or maintenance rules? • Think about what is actually realistic to install on a small survival craft in an emergency—could you really guarantee a fixed height like 8 meters or tune multiple HF frequencies? • Focus on whether the regulation cares more about exact dimensions/measurements, or about using the maximum practicable arrangement given the small size of survival craft.

✅ Before You Answer

• Verify in SOLAS/Radio requirements whether survival craft antenna language mentions HF half‑wave dipoles or just a general type/arrangement • Check if there is any requirement in survival craft rules for weekly or per-voyage testing of the antenna itself (as opposed to the radio equipment on the ship) • Confirm whether any minimum fixed height in meters above the waterline is actually specified for survival craft antennas, or if the rule uses more flexible wording.

What is the antenna requirement aboard a survival craft equipped with a non-portable radiotelegraph installation?

The minimum lifeboat antenna requirement is an HF half-wave dipole capable of efficiently tuning distress frequencies

The antenna must be single wire inverted L type of maximum practicable length and height above the waterline

The antenna must be tested at least once during each voyage and a minimum of once a week on longer voyages

The antenna must be located a minimum of 8 meters above the waterline to insure the safety of passengers
