Equip your vessel with the reliable signal capture of the Furuno GPA021 GPS/DGPS antenna, tailored for seamless integration with the GP170D receiver. This compact H-field antenna excels in challenging marine environments, where metallic structures can interfere with traditional GPS signals. Its innovative design minimizes disruptions, delivering consistent positioning data even on steel-hulled boats or near large metal surfaces.

Key Advantages for Marine Navigation

Marine professionals and recreational boaters alike appreciate the GPA021's ability to lock onto GPS and DGPS satellites swiftly. The 10-meter cable provides flexible mounting options, from masts to railings, without signal degradation. Built to withstand harsh saltwater exposure, it ensures long-term durability without frequent replacements.

• Superior Signal Reception: H-field technology penetrates obstacles better than standard antennas, ideal for crowded decks or enclosed pilothouses.
• Plug-and-Play Simplicity: Direct compatibility with GP170D units means quick setup with minimal wiring hassles.
• Weather-Resistant Build: Sealed construction handles heavy rain, UV rays, and corrosive salt air effectively.
• Extended Reach: Generous 10m cable length allows optimal antenna placement for unobstructed sky view.

Practical Installation Tips

Mount the GPA021 high on your boat for the clearest satellite view, away from radars or HF antennas to avoid interference. Secure it with included hardware, route the cable neatly through conduits, and connect directly to your GP170D—no additional amplifiers needed. Test reception post-installation by checking satellite acquisition time under various conditions. For best results in high-interference areas, position it at least 3 meters from other transmitting equipment.

Enhancing Accuracy in Real-World Scenarios

DGPS support boosts positional accuracy to within meters, crucial for precise anchoring, docking in tight marinas, or following intricate coastal routes. Boaters report fewer signal dropouts during rough seas or when passing under bridges, thanks to the antenna's robust L1 band reception. Pair it with modern chartplotters for a complete navigation upgrade that prioritizes safety and efficiency.

Maintenance for Peak Performance

Keep the antenna surface clean from salt buildup using fresh water rinses after each outing. Inspect cable connections seasonally for wear, and avoid painting over the radome to preserve signal transparency. With proper care, it maintains peak performance across seasons, reducing downtime on the water.
