Product Description

Product Description

GNSS+LTE MIMO Combo Antenna GL228LM for High-Precision Positioning & Data 

The GL228LM is a professional-grade GNSS+LTE MIMO combination antenna designed for high-precision positioning and reliable wireless data transmission. Its GNSS module supports GPS L1/L2, GLONASS G1/G2, COMPASS B1/B2/B3, and Galileo E1/L1/E2/E5b/E6 frequency bands with RHCP polarization, ≤3dB axial ratio, and ≥5dBi peak gain.The integrated LNA provides 40±2dB gain with ≤1.5dB noise figure, ensuring superior signal quality. The LTE MIMO module operates across 698-960MHz/1710-2690MHz with dual-polarized (MAIN:2.5dBi, AUX:2.0dBi) gains and <3.0 VSWR. Built with a 50Ω impedance system, the antenna features Fakra or other compatible connectors and RG316 (GNSS)/RG178*2 (LTE) cables for flexible integration. Its IP67-rated housing (excluding connectors) withstands extreme temperatures (-40°C to +85°C), humidity up to 95%, and vibrations (10-55Hz, 1.5mm amplitude). The compact design enables easy installation on vehicles, drones, or machinery, making it ideal for surveying, fleet management, and industrial IoT applications requiring simultaneous navigation and high-speed data connectivity.
