Connections

3G/2G/CELL
GPS/GLO/QZSS/Galileo/L1
380-470MHz/LPWA/TETRA/UHF

Connector & Cable

• Connector Type: SMA-Male
• Cable Length: 300cm
• Cable Type: RG174

Installation / Environmental

The antenna only measures 99 x 60 x 154 mm and is designed with ASA antenna housing, Zamak antenna base and TPE gasket for durability and protection in wet environments. This antenna can be installed with the secure screw mount that comes with an anti-rotation mechanism preventing any compromise to antenna position. As with all ground plane dependent antennas, it needs to be installed on metal surfaces with the minimum requirement of free space.
Tuned for optimal performance, the GNSS, Cellular and Tetra connections come with 300 cm long RG174 cables and SMA-Male connectors that feed through the anti-rotation screw mount located at the bottom of the antenna. A wide range of alternative connectors and cables are available for customization. Please contact our engineers for assistance in antenna selection or customization requirements.
Products are designed and manufactured without hazardous materials while maintaining full REACH and RoHS compliance.
