High Precision Multi-Band Gnss Antenna with LNA GL-DY231

GPS/Glonass Antenna 

Product Introduction

1. Full-band coverage

Supports 7 major satellite systems (GPS L1/L2, GLONASS G1/G2/G3, Beidou B1/B2/B3, Galileo), achieving global seamless positioning, suitable for devices in any region.

2. High-sensitivity LNA module

Built-in 28dB gain low noise amplifier, noise figure ≤1.5dB, stable signal reception in weak signal areas (tunnels/urban canyons).

3. Industrial-grade environmental protection

-40℃~85℃ wide temperature range operation, IP66 waterproof and dustproof, passed 55Hz vibration test (1.5mm amplitude/2 hours), suitable for harsh scenes such as engineering machinery/ships.

4. Accurate signal quality

≤3dB axial ratio RHCP circular polarization design, voltage standing wave ratio ≤2.0, effectively suppress multipath interference, and improve positioning accuracy to centimeter level.

5. Ready-to-install design

Magnetic/adhesive dual installation, standard RG174 light cable (optional SMA connector), 3-12V wide voltage power supply (≤50mA), compatible with mainstream positioning devices.

Application scenarios

In-vehicle navigation system: commercial fleet management/logistics tracking equipment

Precision agriculture: agricultural machinery automatic driving/soil monitoring instrument

Engineering surveying and mapping: RTK measuring instrument/geological exploration equipment

Maritime equipment: ship navigation system/buoy monitoring

Industrial Internet of Things: drone positioning/smart port crane

FAQ

Q: Does it support Beidou-3 system?

A: Supports Beidou B1/B2/B3 full frequency band, compatible with the latest Beidou-3 signal.

Q: Will the magnetic base interfere with the signal?

A: It uses non-ferromagnetic neodymium magnets, and has no effect on antenna performance after testing.

Q: Can the cable length be customized?

A: Supports RG174/RG316 cable customization (1-10 meters), requiring bulk orders.

Q: How to power it? Do you need an additional circuit?

A: Direct 3-12V DC power supply (typically 5V/35mA), built-in voltage regulator module, no external circuit required.

Q: Can it be used for drones?

A: Net weight <120g, passed 55Hz vibration test, specially designed for drones.

Q: Is the waterproof rating real and effective?

A: IP66 certified (strong water spray proof), no cracking in -40℃ low temperature test.
