Sea-Dog Fixed Antenna Base 4-1/4" Size w/1"-14 Thread Formed 304 Stainless Steel

The Sea-Dog Fixed Antenna Base 4-1/4" Size with 1"-14 Thread is a marine-grade mounting solution engineered for reliable antenna installation on boats, yachts, and watercraft. Designed for professionals and recreational boaters who demand corrosion-resistant hardware in saltwater environments, this fixed antenna base eliminates common installation headaches by integrating cable routing directly into the base structure. Rather than purchasing separate grommets or adapters, this all-in-one base streamlines the mounting process while maintaining structural integrity on curved or flat deck surfaces.

Manufactured from formed 304 stainless steel, this antenna base delivers superior corrosion resistance in harsh marine conditions where standard steel would degrade within months. The 1"-14 thread specification accepts any standard antenna with matching thread pitch, ensuring broad compatibility across commercial and consumer marine equipment. The flange mount design distributes load evenly across the deck or hull surface, reducing stress concentration and preventing water intrusion at the mounting point. Wire feeds directly through the base cavity, creating a clean installation that protects cables from UV exposure and mechanical damage while maintaining a professional finish on deck.

This antenna base is ideal for VHF radio systems, GPS antennas, and communication equipment on vessels ranging from center consoles to superyachts. The compact 4-1/4" form factor fits confined deck spaces without obstructing rigging or walkways, while the 0.4 lb weight ensures negligible impact on vessel balance or weight distribution. Installation is straightforward: secure the flange base with through-bolts or fasteners, route coaxial cable or wire through the integral grommet passage, and thread your antenna into the 1"-14 socket until hand-tight. Ideal for new builds and retrofit applications, this Sea-Dog component has become standard equipment on professional fishing vessels and cruising sailboats.
