Product Description

Product Description

GLB318L High Precision Antenna--High Accuracy Applications
The GLB318L is a compact combination antenna integrating GNSS and LTE connectivity into a single device, ideal for IoT, telematics, and mobile communication systems. The GNSS section supports GPS, QZSS, Galileo, and GLONASS in L1-band, with a gain of 5 dBic and RHCP polarization. The LTE antenna covers 698–960 MHz and 1710–2690 MHz with linear polarization and 2 dBi gain. With an integrated LNA (28±2 dB gain, <1.5 dB noise figure) and wide operating voltage (3–5.5 V DC), the GLB318L offers reliable performance in a small form factor. It features magnet/adhesive mounting, IP66 protection, and RoHS compliance for versatile outdoor and vehicular use.

FAQ

 
Q1: What level of positioning accuracy can this antenna support?

A: This antenna is designed to support centimeter to millimeter-level accuracy when used with a compatible GNSS receiver in RTK (Real-Time Kinematic) or PPK (Post-Processed Kinematic) modes.     Its stable phase center (±5mm) and low axial ratio ensure reliable signal quality for high-precision applications.
 
Q2: Is the antenna compatible with my existing GNSS receiver?

A: Yes, it supports all major GNSS systems (GPS, GLONASS, Galileo, BDS) across multiple frequencies.     It uses a standard SMA connector and operates on 3–12V DC, making it compatible with most industrial and surveying-grade receivers.
 
Q3: Can it be used in harsh environmental conditions?

A: Absolutely.  The antenna is built to operate in temperatures from -40℃ to +85℃ and withstand up to 95% non-condensing humidity, making it suitable for outdoor, marine, and industrial environments.

Q4: How should the antenna be mounted for optimal performance?

A: For best results, mount the antenna on a stable, metallic ground plane with a clear view of the sky.     Ensure the polarization (RHCP) is oriented upward, and avoid obstructions near the antenna's horizon.

Q5: Is the antenna suitable for moving platforms like drones or vehicles?

A: Yes.  Its lightweight design (≤150g), low power consumption, and robust performance across dynamics make it ideal for UAVs, autonomous vehicles, agricultural machinery, and marine navigation systems.
