Sea-Dog White Nylon Fixed Antenna Base – 2-13/16"
A lightweight, corrosion-free deck mount for VHF, AIS, GPS, and other standard marine antennas. This white nylon fixed antenna base from Sea-Dog accepts any antenna with a standard 1"-14 thread and mounts flat to the deck or cabin top using 1/4" RH fasteners — no special hardware required.
The white finish blends cleanly with most fiberglass hulls and topsides, and the nylon construction eliminates any risk of rust staining on your deck or gelcoat. At 2-13/16" in base diameter, it provides a stable footprint without the weight or cost of a stainless steel base — a practical choice for recreational boats where a clean, simple installation is the priority.

Parts Desk Insights
Best Use Case: This base is the right call for recreational powerboats, aluminum fishing boats, and day boats where a clean, lightweight antenna mount is needed and stainless steel isn't a requirement. It's especially popular as a replacement base when the original has cracked or yellowed, and as a secondary mount for a backup or handheld-charging antenna. If you need a stainless steel base for a more demanding installation, see the Sea-Dog 304 SS Fixed Flange Antenna Base – 1-1/2", the Sea-Dog 304 SS Fixed Flange Antenna Base – 4-1/2", or the Sea-Dog SS Fixed Antenna Base – 4" x 2-7/8". To raise the antenna above deck hardware, pair with a Sea-Dog 316 SS Antenna Mount Extension – 12".
Material Note: Nylon bases are well suited for inshore and freshwater use. For offshore or heavy saltwater exposure, a stainless steel base is recommended for long-term durability.
