Furuno GPA021S GPS/DGPS H-Field Antenna for GP170D

The Furuno GPA021S GPS/DGPS H-Field Antenna for GP170D is a precision positioning component engineered for maritime, aviation, and tactical operations requiring differential GPS accuracy. Built for integration with Furuno's GP170D receiver, this antenna delivers the positional intelligence that law enforcement, military, and emergency response teams depend on for mission-critical navigation and asset tracking. High-accuracy positioning has become non-negotiable in modern tactical environments, and this H-Field antenna provides the electromagnetic reception capability necessary to lock and maintain satellite signals in demanding conditions.

The H-Field antenna design employs a specialized radiator pattern optimized for DGPS signal reception, enabling submeter accuracy when paired with Furuno's differential GPS correction infrastructure. At 2.2 pounds, the antenna balances structural durability with weight efficiency—critical for mounted installation on vessels, vehicles, and command centers where mass distribution affects operational performance. The antenna's frequency reception and vertical polarization characteristics are calibrated to reject multipath interference and atmospheric degradation, ensuring stable signal lock even in urban canyons, dense vegetation, or maritime environments where conventional GPS loses coherence.

Operators managing GP170D systems in law enforcement dispatch, Coast Guard operations, or tactical field command will benefit from this antenna's reliability in continuous-duty scenarios. Installation integrates directly with the GP170D receiver through Furuno's standard connector interface, requiring no modification to existing hardware. For organizations operating in GPS-denied or degraded environments, the DGPS capability unlocked by this antenna provides the accuracy margin that separates mission success from operational compromise.
