Sea-Dog Nylon Antenna Stand-Off Bracket
Keep your VHF, AIS, or CB antenna stable and properly positioned with this nylon stand-off bracket from Sea-Dog. Designed to brace long antenna shafts against masts, arches, or cabin sides, the stand-off bracket reduces flex and vibration underway — protecting both the antenna and its base connection from fatigue over time.
The UV-stabilized nylon body resists saltwater corrosion and won't stain surrounding surfaces, while the included stainless steel mounting hardware ensures a secure, long-lasting installation. A practical addition to any antenna setup where the antenna runs alongside a vertical surface and needs a mid-point support.
Key Features
- UV-stabilized nylon construction – corrosion-resistant and lightweight
- Includes stainless steel mounting hardware
- Reduces antenna flex and vibration at speed
- Suitable for mast, arch, or cabin-side mounting
- Compatible with most standard marine antenna shafts
- MPN: 329780-1
Parts Desk Insights
Best Use Case: This bracket is the right solution when you have a tall antenna — typically 8 ft or longer — that whips or flexes excessively at speed, or when the antenna runs alongside a mast or arch and needs a mid-point tie-in to keep it tracking straight. It's commonly used on sportfishers, express cruisers, and sailboats with deck-mounted VHF antennas. For a complete antenna mounting system, pair this with a Sea-Dog Stainless Steel Deck Mount Antenna Base or a Sea-Dog Heavy Duty Stainless Steel Deck Mount Antenna Mount. If your antenna also needs a laydown retention hook, add the Sea-Dog Stainless Steel Laydown Antenna Hook.
Installation Note: Measure the antenna shaft diameter before ordering to confirm the bracket opening is compatible. Stand-off brackets are not universal across all antenna diameters.
