Product introduction
1. Exceptional Gain & Low Noise
Features a built-in LNA with 38±2 dBi gain and ≤2.7dB noise figure, ensuring strong signal reception even in challenging environments while maintaining high signal-to-noise ratio for precise time synchronization.
2. Wide Frequency Coverage & RHCP
Supports GPS L1 (1575.42±5 MHz) and BeiDou B1 (1561.098±2.046 MHz) with right-hand circular polarization. The excellent axial ratio (<4.5dB at center frequency) minimizes multipath errors for reliable positioning.
3. Rugged IP67 Outdoor Design
Fully sealed against dust and water (IP67), resistant to salt fog, humidity, SO₂, and UV radiation. Operates flawlessly from -40°C to +80°C, making it suitable for harsh outdoor installations.
4. Superior Out-of-Band Rejection
Provides up to 70 dBc rejection at ±100MHz from center frequencies, effectively filtering interference from nearby communication bands. This ensures clean signal output and stable GNSS performance.
5. Low Power Consumption & Robust Output
Draws <20 mA from 3–6V DC supply, with >10dBm 1dB compression point. The N‑K female connector offers reliable, low-loss RF connection for permanent or semi-permanent mounting.
Application Scenarios
●Base Station Timing Synchronization – Provides precise GPS/BeiDou time reference for 4G/5G cellular base stations.
●Smart Grid & Power Substations – Delivers accurate timestamping for phasor measurement units (PMUs) and fault recorders.
●Marine & Port Navigation – IP67 corrosion resistance suits vessel tracking, buoy monitoring, and port container management.
●Unmanned Vehicles & Drones – Lightweight, high-gain design ensures stable GNSS lock for agricultural drones and autonomous robots.
●Traffic Management Systems – Used in electronic toll collection (ETC), traffic light synchronization, and fleet tracking infrastructure.
FAQ
Q: What GNSS bands does the GL111 support?
A: It supports GPS L1 (1575.42MHz) and BeiDou B1 (1561.098MHz). It is not designed for GLONASS or Galileo.
Q: What is the connector type?
A: The antenna comes with an N‑K female (N‑K) connector, suitable for outdoor coaxial cables.
Q: Can this antenna be used indoors?
A: While it can work indoors near windows, it is optimized for outdoor use with IP67 protection. Indoor use may reduce signal strength.
Q: What is the operating voltage and current?
A: It requires 3–6V DC (typically 5V) and consumes <20 mA. Power is usually supplied through the coaxial cable (bias tee).
Q: Does it include a built‑in LNA?
A: Yes, the GL111 integrates a low noise amplifier with 38±2 dBi gain and ≤2.7dB noise figure.
Q: What is the beamwidth of this antenna?
A: The 3dB beamwidth is 110°±10°, providing good coverage for most stationary and moving applications.
