Garmin 4FT GMR Fantom Antenna Only
Garmin 4-Foot GMR Fantom Open Array Radar Antenna
Professional Open Array Antenna for Superior Radar Performance
The Garmin 4-foot GMR Fantom open array antenna delivers professional-grade radar performance for vessels requiring enhanced target detection, superior resolution, and extended range capabilities. Designed specifically for integration with Garmin GMR Fantom radar systems, this precision-engineered antenna provides the enhanced directional accuracy and target separation that serious mariners demand for safe navigation and collision avoidance.
Open Array Radar Technology Benefits
Superior Target Resolution
The 4-foot open array design provides significantly better angular resolution compared to radome antennas, enabling clear separation of closely spaced targets. This enhanced resolution is critical for navigating crowded harbors, identifying individual vessels in fleets, and distinguishing between navigation aids and other marine traffic.
Enhanced Range Performance
Open array antennas deliver superior long-range detection capabilities due to their higher gain characteristics and optimized beam pattern. The 4-foot length provides an excellent balance between performance and practicality for vessels requiring professional radar capabilities without the size constraints of larger commercial arrays.
Narrow Beam Width Precision
The extended antenna length creates a narrower horizontal beam width, providing precise bearing accuracy for navigation and target tracking. This precision is essential for accurate plotting, collision avoidance calculations, and precise navigation in restricted waters.
GMR Fantom System Compatibility
Optimized for Fantom Technology
Specifically engineered for integration with Garmin's GMR Fantom radar systems, this antenna is optimized to take full advantage of Fantom's advanced signal processing, target enhancement algorithms, and weather detection capabilities. The combination delivers professional radar performance with user-friendly operation.
Advanced Radar Features Support
When paired with GMR Fantom systems, this antenna enables advanced features including:
- MotionScope Doppler technology for moving target highlighting
- True echo trails for tracking target movement history
- Harbor Mode for enhanced close-range performance
- Weather overlay integration with compatible Garmin displays
- MARPA target tracking for collision avoidance
Seamless Display Integration
The antenna integrates seamlessly with Garmin marine displays including GPSMAP series chartplotters and multifunction displays, providing radar overlay on navigation charts, split-screen radar/chart views, and comprehensive radar control through intuitive touchscreen interfaces.

Frequently Asked Questions
What's the difference between this and a radome antenna?
Open array antennas provide superior range, resolution, and target separation compared to radome antennas. The 4-foot length offers better long-range detection and narrower beam width for precise navigation, though it requires more complex installation.
Can I install this antenna myself?
Professional installation is strongly recommended due to structural mounting requirements, RF safety considerations, and system integration complexity. Certified marine electronics technicians ensure optimal performance and regulatory compliance.
What GMR Fantom systems are compatible?
This antenna is designed for GMR Fantom open array radar systems. Check with Garmin technical support or authorized dealers for specific system compatibility and integration requirements for your vessel application.
How much clearance does the antenna need?
The antenna requires clear 360-degree rotation without obstruction from masts, rigging, or superstructure. Specific clearance requirements depend on mounting height and vessel configuration - consult installation documentation.
Is this antenna suitable for offshore use?
Yes, the 4-foot open array is designed for offshore marine applications and provides the range and resolution needed for safe navigation in coastal and offshore waters, weather detection, and collision avoidance.
Upgrading from Radome Technology
Vessels upgrading from radome to open array technology gain significant performance advantages including enhanced target separation in congested waters, improved long-range detection capabilities, better weather detection performance, and more precise navigation accuracy essential for professional marine operations.
Complete System Requirements
Note: This antenna requires a compatible GMR Fantom radar processing unit, appropriate mounting hardware, and professional installation. The antenna alone does not constitute a complete radar system - it must be integrated with compatible Garmin radar electronics and display units for operation.
