A Reliable, Lightweight Antenna Mount for Everyday Boating
The Sea-Dog White Nylon Ratchet Antenna Mount is a practical, corrosion-proof mounting solution for boaters who want a clean, low-profile antenna installation without the weight or cost of stainless steel. Injection-moulded from UV-stabilized nylon, this mount holds its shape and colour season after season — even in direct sun and salt spray.
The ratchet mechanism lets you adjust your antenna angle for the best signal position, then locks it firmly in place. It accepts any antenna with a standard 1"-14 thread — the universal connection used by virtually all marine VHF, GPS, and AIS antennas — so it pairs with your existing gear right out of the box.

🔧 Parts Desk Insights
Best use case: This mount is the top pick for recreational boaters adding or replacing a VHF or GPS antenna on a fibreglass or aluminum boat where a simple, affordable, and corrosion-free solution is the priority. The ratchet design makes it especially useful on vessels where the antenna needs to be tilted back for low-clearance docking or trailering. It's a go-to for weekend boaters, fishing boats, and smaller cruisers.
Heads up: If you need a fixed (non-adjustable) base, see the Sea-Dog White Nylon Fixed Antenna Base. For a heavy-duty stainless steel adjustable option, consider the Sea-Dog 316 SS Adjustable Deck Mount Antenna Base. If your antenna has a 3/8"-24 thread, you'll need the thread adapter to fit this mount.
