What is the primary purpose of a leakage detector in cable maintenance?

• A. To locate RF leaks and ensure regulatory compliance and minimize interference.
• B. To measure voltage on service drops.
• C. To check fiber optic loss.
• D. To identify faulty power adapters.

Answer: (A)

Leakage detectors are used to locate RF leaks in a coaxial cable system. When shielding or connectors are damaged or not properly sealed, RF energy escapes the system, creating interference and potentially exceeding regulatory emission limits. By sweeping lines and equipment with the detector, technicians can pinpoint the exact leak location and fix it—replacing damaged cable, tightening connectors, or resealing enclosures—and then recheck to verify emissions are within permitted levels. This protects service reliability and helps stay compliant with regulations and avoid interference with other services. Other tasks—measuring service voltage, checking fiber optic loss, or diagnosing faulty power adapters—address different parts of the network and do not involve locating RF leaks.
