ABS radome 1561‑1602MHz GNSS active antenna

Dimension

Product introduction

1. Multi‑GNSS Wideband Coverage

Supports GPS L1 (1575.42MHz), GLONASS L1 (1602MHz), and BeiDou B1 (1561.098MHz) within 1561‑1602MHz. Provides seamless positioning with any major GNSS constellation.

2. High Gain Active LNA with Low Noise

Built‑in LNA delivers 40±2dB gain and ≤2.0dB noise figure, significantly boosting weak satellite signals while minimizing signal degradation for reliable fix in urban canyons or under foliage.

3. Wide Operating Voltage (3–12V DC)

Accepts 3V to 12V DC supply, making it compatible with various receivers, vehicle systems, and industrial equipment without requiring a separate voltage regulator. Current consumption ≤40mA.

4. Robust IP66 Outdoor Enclosure

ABS radome with IP66 protection – dust‑tight and resistant to powerful water jets. Operates from -40°C to +70°C, withstands vibration (10‑55Hz, 1.5mm amplitude), perfect for harsh environments.

5. Excellent Radiation Pattern & Low VSWR

Features 360° horizontal coverage and 5°‑90° vertical coverage with ≤1.5 VSWR (antenna element). The RHCP polarization minimizes multipath errors, while the N‑female connector ensures secure, low‑loss RF connection.

Application Scenarios

●Fleet Management & Vehicle Tracking – Installs on trucks, buses, or construction vehicles for continuous GNSS tracking across multiple constellations.

●Marine & Coastal Navigation – IP66 and ABS housing resist salt spray and moisture on boats, buoys, or port equipment.

●Surveying & Mapping – Provides stable centimeter‑level signal reception for RTK rovers and base stations in open‑sky environments.

●Smart Agriculture – Used on autonomous tractors and sprayers for precise guidance and field mapping.

●Security & Surveillance Systems – Integrates with GNSS time synchronization modules for surveillance cameras, access control, and alarm networks.

FAQ

Q: Which GNSS constellations does the GL541 support?

A: It supports GPS L1, GLONASS L1, and BeiDou B1 (frequency range 1561‑1602MHz). It is not optimized for Galileo.

Q: What is the connector type?

A: The antenna has an N‑female (N‑F) connector, which is durable and weather‑resistant for outdoor RF cables.

Q: Do I need an external LNA?

A: No, the GL541 has a built‑in LNA with 40dB gain. Just provide 3‑12V DC through the coaxial cable (bias tee) and connect to your receiver.

Q: Is the antenna waterproof for continuous rain?

A: Yes, it is rated IP66 – protected against powerful water jets and heavy rain. It is not designed for submersion.

Q: What is the typical current draw?

A: ≤40mA at 5V DC, making it very power‑efficient for battery‑powered or solar‑powered installations.

Q: Can I mount it on a metal pole?

A: Yes, the screw mounting method allows secure attachment to poles, brackets, or flat surfaces. Keep the antenna with clear sky view for best performance.
