Product Overview

Introducing our 1575.42/1561MHz Active GPS/GLONASS Antenna, a high-performance, precision-engineered antenna designed to deliver reliable positioning and timing signals for the most demanding applications. Whether you are building a vehicle tracking system, a precision agriculture solution, a surveying instrument, or a timing synchronization network, this antenna provides the accuracy, durability, and signal integrity required for mission-critical operations.

With a frequency range covering both 1575.42MHz (GPS L1) and 1561MHz (GLONASS L1), this antenna ensures compatibility with both major satellite navigation systems. Its high gain of 27±3dB, low VSWR (≤2.0), and rugged ABS radome make it an ideal choice for both indoor and outdoor installations. The antenna is designed for easy mounting with standard steel mounting kits, ensuring a secure and stable installation on a variety of surfaces.
 

Key Features

• Dual-System Compatibility: Supports both GPS (1575.42MHz) and GLONASS (1561MHz) for enhanced positioning accuracy and reliability.

• High Gain (27±3dB): Provides strong signal amplification for reliable reception, even in weak signal environments.

• Low VSWR (≤2.0): Ensures excellent impedance matching and minimal signal reflection.

• High-Quality Fiberglass Radome: Offers strong protection against UV, moisture, and physical impact (Note: The table specifies ABS material; the features highlight fiberglass radome. Please confirm the exact material).

• Strong Environmental Adaptability: Operates reliably from -30°C to +85°C and humidity up to 95%.

• Standard Steel Mounting Kits: Includes all necessary hardware for secure installation.

• Low Power Consumption: Operates on 3.0V-5V with a current draw of only 7-13mA.

• Compact and Lightweight: Measures Φ96.5*150mm and features a standard N-Female connector.
   

  Performance Breakdown

• Dual-Band Coverage: The antenna supports both 1575.42MHz (GPS L1) and 1561MHz (GLONASS L1) frequencies. This dual-system compatibility ensures that your receiver can lock onto satellites from both constellations, improving positioning accuracy, especially in urban canyons or areas with partial sky visibility.

• High Gain (27±3dB): The antenna features an integrated low-noise amplifier (LNA) that provides a gain of 27±3dB. This high gain compensates for signal loss in the coaxial cable and ensures that the receiver gets a strong, clean signal.

• Low VSWR (≤2.0): A low VSWR indicates good impedance matching. This minimizes signal loss due to reflections, ensuring that the received signal is efficiently transferred to the receiver.

• Low Power Consumption: Operating on a wide voltage range of 3.0V to 5V and drawing only 7-13mA, this antenna is highly efficient and suitable for battery-powered or energy-sensitive applications.

• Vertical Polarization: Matches the polarization of GPS and GLONASS satellite signals, maximizing signal reception.

• High Power Handling (50W): The antenna can handle up to 50W of input power, making it robust and reliable even in high-power transmit environments (though typically used for receive-only applications).
   

  Design Highlights

• High-Quality Radome: The antenna is housed in a white ABS radome. ABS is a tough, impact-resistant plastic that provides excellent protection against UV radiation, moisture, dust, and physical impact. The white color minimizes heat absorption from sunlight, ensuring stable performance in hot environments.

• Compact Size (Φ96.5*150mm): The antenna has a compact, cylindrical form factor that is easy to handle and install. Its size is optimized for both performance and aesthetics.

• Wide Temperature Range (-30°C to +85°C): Operates reliably in extreme climates, from freezing outdoor conditions to hot equipment rooms.

• High Humidity Tolerance (5-95%): Functions effectively in environments with high humidity, making it suitable for tropical and coastal installations.

• Nut Mounting: The antenna features a standard nut mounting design, allowing for secure and easy installation on a variety of surfaces, including vehicle roofs, masts, and equipment enclosures. The standard steel mounting kits ensure a stable and durable installation.
