📝 Starlink Gen 3 RJ45 Waterproof Bulkhead Cable
Upgrade your Starlink Gen 3 install with this waterproof RJ45 bulkhead cable, designed to let you run standard Ethernet while maintaining a sealed, weather-resistant connection. Ideal for RVs, caravans, off-grid cabins, marine installs, or any setup where the cable passes through roofs, exterior walls, junction boxes, or outdoor panels.
⭐ Essential Benefits
• Designed specifically for Starlink Gen 3 Standard systems

• IP68 waterproof – perfect for outdoor and exposed cable runs
• No cutting or crimping of original Starlink cables

⚙️ Functionality
This Gen 3 waterproof bulkhead cable acts as an RJ45 pass-through and coupler, allowing you to:
• Terminate standard Ethernet cable on both sides of a panel, wall, cabinet, or enclosure
• Maintain a sealed IP68-rated connection where the cable passes from inside to outside
• Extend or repair your Starlink Gen 3 network without modifying the factory cable
Simply drill an appropriate hole, fit the bulkhead body through the panel, secure it with the nut, then plug your RJ45 Ethernet cables into each side and tighten the waterproof glands. You now have a secure, weatherproof Ethernet link ready to integrate with your Starlink Gen 3 system via the appropriate Gen 3 adapter/port.
