Waterproof Through-Hull WiFi Antenna, Omnidirectional/Directional for Marine Communication Systems

Product Overview： This waterproof through-hull WiFi antenna is a professional marine-grade wireless antenna tailor-made for shipboard and offshore harsh environments. It supports omnidirectional 360° full coverage and high-gain directional long-distance transmission two optional versions, perfectly adapting different marine WiFi communication demands. Adopting integrated through-hull screw mounting design, it realizes seamless deck penetration installation with excellent hull tightness, effectively preventing seawater leakage and rainwater penetration. The whole antenna features IP68 fully sealed waterproof structure, UV-stabilized and salt-spray resistant housing, capable of long-term stable operation in coastal high-salt, high-humidity and strong ultraviolet marine environments. Widely applied in ship WiFi coverage, offshore buoy wireless transmission, marine survey equipment, yacht intelligent systems and offshore engineering communication scenarios.
Application field： - Ship & Yacht onboard whole-vehicle WiFi network coverage - Offshore monitoring buoys, aquaculture platform wireless data transmission - Marine survey, hydrological detection and offshore engineering communication systems - ROV/AUV underwater supporting

  • Product Description

  • Core Key Features

    1. Dual Versions Optional: Omnidirectional & Directional

    Omnidirectional model provides 360° uniform signal coverage, ideal for full-ship WiFi blind-spot elimination; directional model adopts high-gain directional radiation design to achieve long-distance and anti-interference point-to-point marine wireless transmission, meeting short-range full coverage and long-distance focused communication dual demands.

    2. Professional Through-Hull Screw Mount & Zero Leakage

    Standard marine through-deck threaded installation, equipped with waterproof rubber gasket. It firmly locks on ship hulls, decks and equipment shells, maintaining intact hull tightness without water leakage. The compact embedded structure avoids wind and wave damage, perfectly fitting marine overall installation standards.

    3. IP68 Full Waterproof & Superior Marine Corrosion Resistance

    Full IP68 airtight waterproof certification, resistant to long-term seawater splashing, wave soaking and storm erosion. Adopts UV-proof engineering radome and 316 stainless steel mounting accessories, passing strict salt spray aging test, effectively resisting seawater corrosion, acid and alkali erosion, adapting all-day offshore operation.

    4. 2.4G+5.8G Dual-Band High-Stability Signal

    Covers full WiFi mainstream frequency bands of 2400–2500MHz and 5725–5850MHz. Optimized RF impedance matching design reduces marine environment signal attenuation and multipath interference, ensuring stable, low-latency WiFi connection even in complex offshore electromagnetic environments.

    5. Flexible Customization & Wide Compatibility

    Supports customized waterproof cable length and multiple connectors including SMA, N-type and BNC. Compatible with marine WiFi routers, industrial wireless bridges, ship monitoring systems and offshore intelligent communication equipment, plug-and-play with strong universality.
