DNC-2056 Underwater Waterproof Bulkhead Connector for GPS, WLAN & WiFi Antennas
The DNC-2056 is a professional underwater waterproof RF bulkhead connector designed for GPS, WLAN, WiFi, WISP, WiMax, LMR, RFID, and high-frequency antenna systems. It creates a secure waterproof connection point between an external antenna cable and internal underwater electronics, making it suitable for marine, industrial, scientific, offshore, and custom underwater communication projects.
Built for demanding underwater environments, the DNC-2056 combines a marine-grade aluminum body, hard anodized coating, gold-plated brass contacts, and Dive And See Water Block Technology to help protect the housing vacuum and reduce flooding risk if the external cable is damaged.
Key Benefits
- Designed for RF antenna systems: Supports GPS, WLAN, WiFi, WISP, WiMax, LMR, RFID, telemetry, and other high-frequency antenna applications.
- Professional waterproof bulkhead connection: Provides a reliable pass-through point between an external antenna cable and internal electronics inside an underwater housing or enclosure.
- Integrated Water Block protection: Helps maintain vacuum integrity inside the housing and adds protection against water ingress through a damaged external cable.
- Depth rated to 160 meters: Designed for underwater operation up to 240 PSI / 160 m / 525 ft.
- Marine-grade construction: Hard anodized aluminum body supports long-term durability in harsh marine, offshore, and industrial environments.
- Gold-plated contacts: Supports stable conductivity for reliable RF signal transmission.
- Protective cap included: Helps protect the connector during transport, storage, and field preparation.
Why DNC-2056 Is Different
Unlike a simple waterproof penetrator, the DNC-2056 is built specifically for high-frequency underwater RF communication and antenna integration. It is intended for systems where signal integrity, waterproof reliability, vacuum protection, and serviceability matter in real field conditions.
This makes the DNC-2056 a practical choice for underwater antenna installations, surface communication links, ROV-related electronics, marine monitoring systems, and custom underwater enclosures where a dependable RF bulkhead connection is required.
Water Block Technology
The DNC-2056 includes an internal Water Block safety system. This feature is designed to help preserve the vacuum inside the underwater housing and provide an additional barrier against water migration if the external cable or connector is damaged during use.
For professional underwater systems, this is an important difference. The external cable is often the most exposed part of the system. Water Block Technology helps reduce the chance that external cable damage will immediately compromise the electronics inside the housing.
Compatibility & Ecosystem
The DNC-2056 is designed to work with Dive And See underwater high-frequency cable systems and custom RF antenna assemblies.
Custom cable lengths, RF connector types, internal cable configurations, antenna-side connectors, and housing integration options are available for OEM, industrial, research, military, commercial, and marine projects.
Typical System Layout
External antenna or RF cable → DNC-2056 waterproof bulkhead connector → internal RF cable → underwater electronics, modem, GPS receiver, telemetry module, WiFi device, or custom communication system.
Important Tightening Warning
Before underwater use, always verify that the external connector coupling nut is fully tightened by hand. Do not use pliers or tools. Improperly tightened underwater connectors may allow water intrusion and may damage the equipment or underwater housing.
