Designed with commercial-grade materials, this antenna features brass and copper elements to ensure durability and optimal signal transmission. Its 4-foot height and omni-directional radiation pattern provide broad coverage, making it ideal for marine environments where consistent communication is critical. The mast mounting sleeve allows for secure installation, either with included U-bolts or by straps using steel banding (not supplied). The antenna's impedance is set at 50 ohms, with a gain of 3dB, and it is capable of handling input power up to 100 watts, supporting a wide range of AIS transceivers. The SO-239 connector at the base simplifies integration with existing radio systems, while the vertical polarization ensures efficient signal propagation over the water. This antenna is built to meet the broader bandwidth requirements of popular AIS transceivers, with a bandwidth of 6.0 MHz at 1.5:1 SWR, centered around 156.8 MHz, achieving an SWR of 1.5:1 for optimal performance. Its construction is designed for longevity in marine conditions, backed by Shakespeare's 2-year limited warranty. Please note that coax cable is sold separately, and the antenna's DC ground feature indicates it does not provide grounding, which is typical for marine VHF antennas. Whether used for commercial or recreational vessels, the Shakespeare 396-1-AIS antenna ensures clear, reliable communication essential for navigation and safety at sea.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003e4-foot vertical omni-directional VHF marine antenna designed for AIS transceivers\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstructed with brass and copper elements for durability and reliable signal transmission\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes mast mounting sleeve with U-bolts for secure installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSupports a bandwidth of 6.0 MHz within 2:1 SWR at 156.8 MHz for broad compatibility\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eImpedance of 50 ohms with a gain of 3dB for effective signal coverage\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCapable of handling up to 100 watts of input power for various AIS transceivers\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSO-239 connector at the base for easy connection to marine radio systems\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVertical polarization with omni-directional radiation pattern for 360-degree coverage\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for marine environments with corrosion-resistant materials and a rugged build\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBacked by Shakespeare’s 2-year limited warranty for quality assurance\u003c\/li\u003e\u003c\/ul\u003e","brand":"Shakespeare","offers":[{"title":"Default Title","offer_id":44535343120426,"sku":"16286","price":172.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/16286XL.jpg?v=1783286196","url":"https:\/\/atticusgoods.com\/products\/shakespeare-396-1-ais-broadband-vhf-marine-ais-antenna-for-enhanced-marine-communications","provider":"Atticus Goods","version":"1.0","type":"link"}
