Investment cast from 316 stainless steel, this adjustable deck mount features dual swivelling mounts and an integral cable feed system — letting you position your antenna at the ideal angle while routing the coax cleanly through the base with no exposed cable on deck.\u003c\/p\u003e\u003cp\u003eThe wide 2-1\/2\" footprint and robust 316 SS construction make this one of the most stable and corrosion-resistant fixed antenna bases available for deck or cabin top installation. At 4-1\/2\" tall, it provides meaningful elevation above the mounting surface without requiring a separate extension for most applications.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInvestment cast 316 stainless steel – offshore-grade corrosion resistance\u003c\/li\u003e\n\u003cli\u003eDual swivelling mounts – full directional antenna adjustment\u003c\/li\u003e\n\u003cli\u003eIntegral cable feed system – coax routes through the base, no exposed cable\u003c\/li\u003e\n\u003cli\u003eStandard 1\"-14 thread – fits most marine antennas\u003c\/li\u003e\n\u003cli\u003eDimensions: 2-1\/2\" W x 2-15\/16\" L x 4-1\/2\" H\u003c\/li\u003e\n\u003cli\u003eWide base footprint for maximum stability on deck\u003c\/li\u003e\n\u003cli\u003eMPN: 329230-1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e This base is the go-to choice for a permanent, high-quality VHF or AIS antenna installation on a deck or cabin top where you want adjustability, hidden coax routing, and offshore-grade materials in a single unit. The wider base footprint compared to narrower fixed bases gives it superior stability on planing hulls and in rough water.
