Product Introduction

  1. Dual GNSS+LTE MIMO Integration
    Combines GNSS (GPS L1/B1/G1) and LTE (698-2690MHz) in one compact design, ideal for IoT devices, vehicle telematics, and smart city applications requiring simultaneous positioning and data transmission.

  2. High-Performance Ceramic Antenna
    Features a ceramic element with RHCP polarization, return loss <-15dB, and stable phase center, ensuring reliable sub-meter accuracy for navigation and tracking systems.

  3. Low-Noise Amplifier (28±3dB Gain, ≤1.5dB Noise)
    Enhances weak GNSS signals while minimizing interference, critical for urban canyons or remote areas with limited satellite visibility.

  4. Robust Build & Easy Installation
    IP67-rated PC+ABS radome, 3M adhesive mounting, and FAKRA connectors ensure durability and quick deployment in harsh environments like construction sites or fleet vehicles.

  5. Broad LTE Compatibility
    Supports LTE bands 698-960MHz and 1710-2690MHz with V.S.W.R ≤3, enabling seamless 4G/5G connectivity for real-time data sharing in smart agriculture or logistics.

Application scenarios

  • Vehicle Telematics: Enables real-time fleet tracking and driver behavior monitoring.

  • Smart Agriculture: Supports precision farming equipment with GPS-guided operations.

  • IoT Asset Tracking: Monitors high-value shipments or equipment in transit.

  • Drone Navigation: Ensures stable LTE connectivity and accurate positioning for aerial surveys.

  • Urban Infrastructure: Integrates into smart city sensors for traffic management.

FAQ

Q:Is this antenna compatible with 5G networks?
A:It supports LTE bands up to 2690MHz; confirm 5G compatibility with your carrier’s frequency range.


Q:How to mount the antenna securely?
A:Use the 3M adhesive backing for permanent installation on flat surfaces like vehicle roofs or equipment panels.


Q:What power supply does the LNA require?
A:Operates on 3~5.5V DC with ≤20mA current, compatible with most IoT devices or vehicle systems.


Q:Can it withstand extreme temperatures?
A:Designed for harsh conditions but verify specific temperature ratings with the manufacturer.


Q:Does it support GLONASS or Galileo?
A:Focused on GPS L1/B1/G1; check customization options for additional GNSS systems.


Q:How to reduce LTE interference with GNSS signals?
A:The MIMO design and optimized V.S.W.R minimize cross-system interference.
