{"product_id":"west-1628","title":"Shakespeare Galaxy 4ft 3dB AIS Antenna SHA-5396-AIS","description":"\u003cp\u003eThe Shakespeare Galaxy \u003cstrong\u003e5396-AIS\u003c\/strong\u003e is a 4 ft marine AIS antenna designed for Automatic Identification System transceivers that require broader VHF bandwidth than a standard narrow-purpose antenna setup. It uses a center-fed 1\/2-wave coaxial sleeve design with commercial-grade fiberglass construction, brass and copper elements, and Shakespeare’s Galaxy high-gloss white polyurethane finish for long-term marine durability. The antenna includes a stainless steel 1”-14 threaded ferrule, 20 ft of RG-8X coax, and a supplied PL-259 connector.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4 ft \/ 1.21 m AIS antenna with \u003cstrong\u003e3dB gain\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eBroadband VHF design for AIS transceiver use\u003c\/li\u003e\n\u003cli\u003eCenter-fed 1\/2-wave coaxial sleeve construction\u003c\/li\u003e\n\u003cli\u003eCommercial-grade fiberglass body with high-gloss, non-yellowing Galaxy white finish\u003c\/li\u003e\n\u003cli\u003eBrass and copper internal elements\u003c\/li\u003e\n\u003cli\u003eStainless steel ferrule with standard \u003cstrong\u003e1\"-14 thread\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eIncludes \u003cstrong\u003e20 ft RG-8X coax\u003c\/strong\u003e and \u003cstrong\u003ePL-259 connector\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMaximum input power: \u003cstrong\u003e50 watts\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eBandwidth: \u003cstrong\u003e5 MHz within 2.0:1 VSWR\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eNominal SWR: \u003cstrong\u003e1.5:1 at 156.8 MHz\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eDC grounded design; antenna may read shorted during a continuity test\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplication Compatibility\u003c\/h2\u003e\n\u003cp\u003eThis antenna is intended for AIS systems on boats using compatible AIS receivers or transceivers. It is a good match for installations where a compact 4 ft antenna is preferred, such as smaller vessels, hardtop installations, arch mounts, and locations where a full 8 ft antenna is not practical. Shakespeare’s catalog lists the 5396-AIS as a Galaxy-series AIS antenna with a standard 1”-14 mount type and suggested mounts such as Shakespeare 4187 or 4187-HD.\u003c\/p\u003e\n\u003ch2\u003eSerial Number Fitment Notice\u003c\/h2\u003e\n\u003cp\u003eMarine antennas do not use engine serial-number fitment, but compatibility should still be checked against the AIS unit, mounting location, cable routing, connector requirements, and available antenna mount. Confirm that the boat’s AIS equipment uses the correct VHF\/AIS antenna connection before ordering.\u003c\/p\u003e\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eReplace the AIS antenna if the fiberglass body is cracked, the ferrule is damaged, the cable is cut or corroded, the connector is compromised, or AIS transmit\/receive range has become unreliable after checking the AIS unit and wiring. A damaged antenna or coax connection can reduce AIS performance even when the transceiver is working properly.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eMount the antenna as high and clear of obstructions as practical for best AIS range. Use a compatible 1”-14 marine antenna mount, route the coax carefully to avoid sharp bends and chafe points, and install the PL-259 connector according to the connector instructions. Keep AIS\/VHF antennas properly spaced from other antennas and strong RF sources where possible.\u003c\/p\u003e\n\u003ch2\u003eAlternate \/ Superseded Part Numbers\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eShakespeare 5396-AIS\u003c\/li\u003e\n\u003cli\u003e5396AIS\u003c\/li\u003e\n\u003cli\u003e5396 AIS\u003c\/li\u003e\n\u003cli\u003eSHA-5396-AIS\u003c\/li\u003e\n\u003cli\u003eUPC: \u003cstrong\u003e719441200343\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eParts Desk Insight\u003c\/h2\u003e\n\u003cp\u003eThe 3dB gain is a practical choice for smaller or more active boats because it gives a broader radiation pattern than higher-gain antennas. For AIS, the cleanest install is usually the one with the antenna mounted high, the cable kept in good condition, and the connector installed properly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships in 1–3 business days for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43564237226020,"sku":"SHA-5396-AIS","price":511.96,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/0986da5a-c7a9-4e6b-923e-0c1870c0082d.png?v=1777507974","url":"https:\/\/marisolmarine.com\/products\/west-1628","provider":"Marisol Marine Company","version":"1.0","type":"link"}
