Investment cast from 316 stainless steel — the marine grade — it delivers the corrosion resistance and structural rigidity needed for permanent offshore and coastal installations where lesser materials fail over time.\u003c\/p\u003e\u003cp\u003eThe standard 1\"-14 thread fits the vast majority of marine antenna bases and antennas, making it a direct drop-in extension for most existing setups. At 24\" of additional height, it's the right choice when you need meaningful elevation gain — clearing obstructions, improving line-of-sight range, or getting above a hardtop or arch.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInvestment cast 316 stainless steel – maximum marine corrosion resistance\u003c\/li\u003e\n\u003cli\u003eStandard 1\"-14 thread – compatible with most marine antenna bases and antennas\u003c\/li\u003e\n\u003cli\u003e24\" length for significant elevation gain\u003c\/li\u003e\n\u003cli\u003e1-1\/16\" outer diameter, 13\/16\" tube wall\u003c\/li\u003e\n\u003cli\u003eSuitable for permanent offshore and coastal installations\u003c\/li\u003e\n\u003cli\u003eMPN: 329536-1\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 the right call when your antenna is mounted low — on a deck base or cabin top — and you need to clear a hardtop, T-top, or arch to improve VHF range or GPS sky view. The 24\" length is best suited to situations where a 12\" extension won't clear the obstruction. If 24\" is more than you need, see the \u003ca href=\"\/products\/west-4531\"\u003eSea-Dog Stainless Steel 12\" Antenna Mount Extension\u003c\/a\u003e or the \u003ca href=\"\/products\/west-4532\"\u003eSea-Dog Stainless Steel 12\" Antenna Mount Extension\u003c\/a\u003e for a shorter reach.
