The reviewer found its silver-plated outer conductor, copper inner conductor and stainless steel mounting sleeve combine into a durable unit that performs well aloft on hardtops and T-tops. The integrated Type SO-239 connector inside the sleeve and the suggested Shakespeare 4187-HD ratchet mount make it easy to install and stow, which is the single biggest reason to buy.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSilver-plated outer conductor:\u003c\/strong\u003e improves conductivity and resistance to corrosion for long-term signal stability in a saltwater environment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCopper inner conductor:\u003c\/strong\u003e provides a reliable core for consistent VHF transmission and reception across the marine band.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStainless steel mounting sleeve:\u003c\/strong\u003e offers a sturdy attachment point that withstands vibration and outdoor exposure on boats.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in Type SO-239 connector:\u003c\/strong\u003e allows quick mounting and dismounting for stowage without complex coax termination work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact 4 ft length with 3 dB gain:\u003c\/strong\u003e delivers improved range and performance while remaining small enough for T-tops and hardtops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase III electronic elements:\u003c\/strong\u003e the commercial-grade internals are positioned with an ethafoam spacer system for consistent performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Shakespeare 6400-R suits owners of center consoles, sportfishing boats and cruisers who need a dependable VHF antenna that does not dominate the profile of the vessel.
