Investment cast from 316 stainless steel — the same alloy used in offshore deck hardware — it provides the structural rigidity and saltwater resistance needed for a permanent, low-maintenance installation on any vessel.\u003c\/p\u003e\u003cp\u003eThe standard 1\"-14 thread fits the vast majority of marine antenna bases and antennas, making this a straightforward drop-in riser for most existing setups. At 12\", it's the right amount of elevation for clearing low obstructions, improving antenna line-of-sight, or simply getting the antenna above deck clutter without the bulk of a longer extension.\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\u003eStandard 1\"-14 thread – compatible with most marine antenna bases and antennas\u003c\/li\u003e\n\u003cli\u003e12\" length for moderate elevation gain\u003c\/li\u003e\n\u003cli\u003e1-1\/16\" outer diameter, 13\/16\" tube wall\u003c\/li\u003e\n\u003cli\u003eSuitable for permanent saltwater installations\u003c\/li\u003e\n\u003cli\u003eMPN: 329532-1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e This extension is ideal when your antenna base is mounted at deck level or on a cabin top and needs a modest height boost to clear a rail, windshield frame, or low arch — without the reach of a 24\" extension. It's a popular choice on center consoles, walkarounds, and express cruisers where a short riser keeps the antenna visible and accessible without adding excessive leverage on the base.
