The Shakespeare Phase III 6396-AIS-R is a 4-foot fibreglass antenna tuned to cover both the standard VHF marine band and the dedicated AIS frequencies (161.975 \u0026amp; 162.025 MHz) — eliminating the need for a separate AIS antenna and the associated splitter or second cable run. The integrated ratchet mount adds practical versatility for trailering, bridge clearance, and covered slip storage.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDual-purpose AIS + VHF tuning — one antenna handles both your radio and AIS transponder\u003c\/li\u003e\n\u003cli\u003eOptimised for AIS frequencies (161.975 \u0026amp; 162.025 MHz) and the full VHF marine band\u003c\/li\u003e\n\u003cli\u003e3 dBd gain for reliable range on both VHF voice and AIS target acquisition\u003c\/li\u003e\n\u003cli\u003e4-foot (1.2 m) fibreglass construction — lightweight, rigid, and corrosion-resistant\u003c\/li\u003e\n\u003cli\u003eIntegrated ratchet mount folds and locks at multiple angles — no tools required\u003c\/li\u003e\n\u003cli\u003eStandard 1–14 UNS thread base fits most marine antenna mounts and rail brackets\u003c\/li\u003e\n\u003cli\u003eUV-stabilised fibreglass radome for long-term durability in the marine environment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy a Dedicated AIS Antenna?\u003c\/h3\u003e\u003cp\u003eUsing a standard VHF antenna with an AIS splitter introduces insertion loss that can reduce AIS target range and transmission reliability.
