DNC-2192 – Fully Submersible Wi-Fi Antenna (Permanent Cable Version)
The DNC-2192 is a professional-grade fully submersible Wi-Fi antenna engineered for harsh marine and underwater environments. Based on the proven RF design of DNC-2129, this version features a permanently attached waterproof high-frequency coaxial cable (up to 3 m), allowing the antenna to be installed independently from the main receiver/transmitter at distances of up to 3 meters.
The DNC-2192 is ideal for boats, yachts, buoys, underwater housings, ROVs, and aquatic research systems where reliable surface Wi-Fi connectivity is required in wet, exposed, or submerged conditions.
Key Features
- Fully submersible Wi-Fi antenna for marine and underwater systems
- Permanent waterproof 50-Ohm coaxial cable for remote antenna positioning
- Cable length: up to 3 m (custom lengths available)
- Cable OD: 5 mm
- Dual-band operation: 2.4 GHz / 5 GHz
- High gain: 8 dBi omnidirectional radiation
- M18 threaded mount for secure installation
- Body: marine-grade aluminum with hard anodized coating
- Designed for long-term outdoor, high-humidity, and water-exposed environments
How the DNC-2192 Works
Water strongly attenuates radio signals, so underwater Wi-Fi systems typically operate by extending the antenna to the surface rather than transmitting through water over long distances.
The DNC-2192 is used as part of a surface-tethered communication system:
- Mount the antenna on a buoy, vessel, or external housing location.
- Route the waterproof RF cable to your surface equipment.
- Connect to a standard Wi-Fi router, access point, smartphone, tablet, laptop, or wireless bridge.
This approach provides stable and reliable Wi-Fi connectivity above the waterline for submerged equipment such as cameras, sensors, or ROV systems.
Typical Applications
- Boats and yachts (reliable Wi-Fi in wet, exposed marine environments)
- Buoy-mounted communication systems for surface Wi-Fi connectivity
- Underwater drones / ROVs with surface-tethered wireless links
- Aquatic research equipment (sensors, telemetry, monitoring nodes)
- Industrial installations with high humidity or direct water exposure
