Submersible Double Depth Antenna (SDDA)
The Submersible Double Depth Antenna (SDDA) enables electromagnetic detection of underwater cables and pipelines from surface vessels or shoreline positions. This remote sensing device contains dual-coil antenna elements sealed within waterproof housing rated for continuous submersion. Operators lower the antenna into water bodies using attached support cables available in 10-meter, 50-meter, or custom 100-meter lengths. The unit connects to compatible cable locators through sealed connector assemblies that maintain signal integrity while preventing water ingress into receiver circuits.
Two frequency variants serve different detection requirements: the 640Hz model traces power cables and cathodic protection systems operating at lower frequencies, while the 8kHz version detects higher-frequency transmitter signals applied to telecommunication cables and metallic pipelines. The double-depth antenna configuration provides directional guidance through differential signal measurement between coil pairs, allowing operators to determine lateral position relative to submerged utilities. Cable lengths accommodate varying water depths from shallow harbor installations to deeper river crossings and offshore approaches.
Marine construction contractors use the Submersible Double Depth Antenna (SDDA) to verify subsea cable routes before anchor deployment or dredging operations commence in harbor channels. Military amphibious engineering units trace underwater power lines supplying coastal defense installations and pier facilities. Navy diving teams locate submerged communication cables crossing between island installations and mainland support facilities. Airforce contractors mapping utilities at seaplane bases trace electrical services running beneath dock structures and through shallow water approaches to aircraft moorings.
Tactical Supply Pakistan provides submersible detection equipment for professionals locating buried utilities beneath waterways and coastal zones. The company supports marine construction and infrastructure teams requiring underwater electromagnetic tracing capability.
Can the submersible antenna distinguish between multiple parallel cables on the seabed?
Signal discrimination depends on cable spacing and applied frequencies; closely spaced cables may produce overlapping fields requiring systematic signal tracing to isolate individual conductors.
