Waterproof Underwater WiFi Antenna, Omnidirectional/Directional for Subsea Wireless Communication Systems

Product Overview： This waterproof underwater WiFi antenna is a professional subsea-grade wireless solution exclusively engineered for harsh underwater and offshore marine environments. It features two optional configurations: omnidirectional 360° full signal coverage and high-gain directional long-distance targeted transmission, fully catering to diverse short-range coverage and long-distance point-to-point subsea wireless communication requirements. Adopting an integrated fully sealed submersible design, this antenna effectively solves signal attenuation and unstable connection issues caused by water medium absorption and seabed multipath reflection. The IP68 full airtight waterproof structure, paired with UV-stabilized and salt-spray resistant housing, enables long-term continuous submersion in fresh water, brackish water and deep coastal seawater. It delivers reliable low-latency underwater video feedback and sensor data transmission, widely applicable to subsea robot operation, underwater monitoring equipment, marine survey systems and various subsea engineering wireless communication scenarios.

Application field： - ROV/AUV underwater robot real-time video transmission & wireless control - Subsea monitoring buoys, underwater aquaculture equipment data collection - Marine hydrological survey, subsea terrain mapping and offshore subsea engineering

Product Description

Core Key Features
1. Dual Optional Versions for All Subsea Scenarios
The omnidirectional antenna provides 360° uniform signal coverage, eliminating wireless blind spots for mobile underwater equipment such as ROVs and floating monitoring devices. The high-gain directional antenna supports long-distance anti-interference point-to-point transmission, perfectly suitable for fixed subsea monitoring stations and cross-water area data interaction, covering full subsea communication needs.
2. IP68 Full Submersible & Extreme Subsea Durability
Certified with IP68 full sealed waterproof rating, the antenna supports long-term continuous underwater operation. Built with high-strength anti-UV radome and premium 316 stainless steel structural accessories, it passes strict industrial salt spray and hydraulic pressure aging tests, resisting seawater corrosion, water pressure impact, tidal erosion and strong ultraviolet radiation for 24/7 stable subsea operation.
3. Water Medium Adaptive RF Optimization
Custom-tuned professional RF circuit design specifically compensates for natural signal attenuation in water media. It suppresses subsea multipath interference caused by seabed and riverbed reflections, maintaining stable, low-loss and low-latency WiFi connection in complex turbid water and shallow/deep subsea environments, far more adaptable than ordinary terrestrial WiFi antennas.
4. 2.4G+5.8G Dual-Band Stable Transmission
Covers mainstream dual WiFi frequency bands of 2400–2500MHz and 5725–5850MHz. The optimized impedance matching structure enhances anti-electromagnetic interference capability in marine environments, ensuring smooth real-time transmission of underwater high-definition videos, environmental sensing data and equipment operating data without signal drop or distortion.
5. Flexible Customization & Broad Compatibility
Supports customized underwater waterproof cable lengths and multiple mainstream RF connectors including SMA, N-type and BNC. It is perfectly compatible with underwater WiFi modules, subsea wireless routers, industrial wireless bridges, ROV control systems and underwater monitoring hosts, featuring plug-and-play convenience and strong universal adaptability.
