Achieve unparalleled accuracy and signal reliability for all your critical navigation and timing applications with our high-gain 1228MHz GPS/GNSS Omni External Antenna. Engineered for demanding environments, this antenna is the ideal external component for professional-grade receivers requiring robust, consistent signal acquisition across the Global Positioning System (GPS) and other Global Navigation Satellite Systems (GNSS). Its specific tuning for the L2 frequency band (1228 MHz center) ensures high-precision performance, while the 5dBi gain and rugged N-Male connector make it the definitive choice for permanent outdoor installations.
Uncompromising Technical Specifications and Design
This external antenna is designed not just for signal reception, but for resilience and long-term accuracy, making it a cornerstone for precise positioning technology.
Optimized for GNSS L2 Frequency Band
The antenna is precisely tuned to the 1228MHz frequency, which corresponds to the L2 signal used by the GPS constellation. This frequency is crucial for advanced GNSS receivers that utilize dual-frequency processing to effectively mitigate atmospheric errors (ionospheric delay), leading to significantly higher accuracy in positioning, particularly in Real-Time Kinematic (RTK) and Precise Point Positioning (PPP) applications. While this antenna is centered on L2, its broad bandwidth and high sensitivity ensure compatibility and excellent performance with signals frm other adjacent GNSS constellations, including GLONASS, BeiDou, and Galileo L1 and L5 bands, depending on the specific model variation.
High-Gain 5dBi Performance
Featuring a powerful 5dBi gain, this antenna dramatically enhances the sensitivity of your receiver system. High gain means the antenna can capture fainter satellite signals and maintain a stronger, more stable lock, especially in challenging environments where line-of-sight to the satellites is partially obstructed, such as urban canyons or areas with heavy foliage. This enhanced signal strength translates directly into faster time-to-first-fix (TTFF) and improved reliability of continuous tracking, minimizing dropouts.
Omnidirectional Signal Reception
The antenna utilizes an omnidirectional radiation pattern, allowing it to receive signals from satellites across the entire visible sky dome simultaneously. This design is critical for permanent or stationary installations where the antenna cannot be manually repositioned to track satellites. Its uniform sensitivity ensures that the receiver has access to the maximum number of satellites above the horizon at any given moment, optimizing the geometric distribution of the constellation for the highest possible positioning accuracy (low Dilution of Precision - DOP).
Professional-Grade N-Male Connector
For a secure, weatherproof, and highly durable connection, the antenna terminates with an N-Male connector. The N-Type connector is the industry standard for outdoor and high-power radio frequency applications, known for its robust construction, excellent vibration resistance, and superior performance at these frequencies. The threaded coupling mechanism ensures a tight, reliable seal, preventing moisture ingress and signal degradation over years of outdoor exposure.
Essential Application Scenarios
The need for highly accurate, externally mounted GNSS reception is critical across several professional and industrial sectors.
Surveying and Mapping (Geomatics)
For land surveyors, civil engineers, and geographical information system (GIS) professionals, centimeter-level accuracy is non-negotiable. This external antenna provides the necessary stable L2 signal required for base stations or mobile rovers used in RTK/PPK surveying workflows. Its robustness ensures that field data collection remains reliable, even in harsh weather or remote locations.
Critical Infrastructure and Timing
Precise timing is vital for synchronizing power grids, cellular networks (e.g., 5G base stations), and financial trading systems. When integrated into a GNSS timing receiver or master clock, this high-gain antenna ensures the system maintains a constant, high-integrity lock on satellite signals, providing the nanosecond accuracy required for network synchronization and operational stability.
Permanent Scientific and Environmental Monitoring
Scientists and researchers depend on long-term, continuous, and reliable positioning data for projects like tectonic plate monitoring, atmospheric research, and environmental displacement tracking. Permanently mounted on monuments or remote stations, this antenna provides the consistent, high-quality signal required for these sensitive, long-duration measurements.
Autonomous Vehicles and Robotics
While smaller antennae are used for consumer applications, high-reliability autonomous systems, including heavy-duty agricultural machinery, port automation vehicles, and industrial drones, require a robust external antenna for primary positioning. The 5dBi gain ensures that the sophisticated on-board navigation system receives the continuous, high-fidelity data streams needed for safe and accurate navigation and operation.
