Marine and Maritime Navigation
Designed to withstand corrosive environments, this antenna ensures reliable positioning at sea:
Vessel Tracking: Providing continuous, clear positioning data for navigation systems, autopilots, and maritime safety applications (e.g., AIS).
Offshore Operations: Its robust, IP-rated enclosure is ideal for long-term deployment on oil rigs, research vessels, and buoys.
Engineering Excellence: The Power of Active Gain
The true performance distinction of this antenna lies in the combination of its 5 dBi passive ceramic patch gain and a high-quality Low Noise Amplifier (LNA).
The Role of High Gain (5 dBi)
The 5 dBi figure refers to the antenna element's inherent ability to concentrate the received satellite signal. This high initial gain is critical for capturing signals that have travelled long distances or been attenuated by the atmosphere.
The Low Noise Amplifier (LNA)
The integrated LNA is a crucial feature that converts the passive antenna into an Active GPS Antenna. The LNA circuit immediately boosts the weak satellite signal before it travels down the cable. Critically, it does this while adding minimal electronic noise (defined by the low Noise Figure). This signal boost helps overcome cable attenuation (loss), ensuring the GPS receiver chip receives a clean, strong signal, which directly translates into:
Faster Acquisition: Shorter Time-to-First-Fix (TTFF).
Improved Tracking: Better ability to maintain lock on a high number of satellites, especially when the line of sight is partially obscured.
Durability and Installation
Housed in a rugged, UV-resistant, and IP67 rated enclosure, the antenna is fully protected against dust ingress and immersion in water. This makes it perfect for permanent outdoor mounting, guaranteeing long-term, reliable performance regardless of weather conditions. Various mounting options (magnetic, screw-mount, or adhesive) are typically available to facilitate quick integration into any existing system or enclosure.
Optimize Your GNSS System
Investing in the 1575 MHz 5 dBi High Gain GPS Antenna is investing in the reliability and accuracy of your location-based operations. Its exceptional gain and advanced active circuitry ensure that your GPS receiver is performing at its absolute peak, maximizing data fidelity and minimizing downtime due to signal loss.
