Suggested applications include: 

  • Navigation
  • Automotive / Transportation 
  • Fleet Management 
  • M2M
  • Telematics

This antenna is designed with a pre-filter and high active gain of 28 dB @ 2.7 V and will maintain constant M2M signal strength for maximum precision. 

Installation / Environmental

The antenna housing and base are manufactured with high quality ASA material that is designed to operate in temperatures ranging -40C to +85C without any compromise to performance. The small box-shaped antenna housing measures 28 x 25 x 13 mm and comes with a magnetic mount that allows for temporary or long-term installations on metal surfaces such as vehicles, poles, and buildings. This antenna is IP67 certified.

2J4F01MGF includes a standard SMA-Male connector and a 300 cm long flexible RG174 cable tuned for optimal GNSS performance. We offer a large range of alternative connectors and cables to meet any customization needs. It is important to match the right antenna with the job and our expert engineers are available for installation support, any customization needs and antenna selection support. 

All our products are designed with the environment in mind and manufactured without hazardous materials with full REACH and RoHS compliance.
