Antenna Description

Low Profile Antenna  With Exceptional Precision and Reliability for Global Navigation

2J7401MGF is a high-efficiency customizable waterproof antenna ideal for external use on vehicles and outdoor assets worldwide. This low-profile ground plane independent antenna covers all the major GNSS bands, including GPS, GLONASS, QZSS and Galileo standards. This compact antenna is ideal for the automotive and transportation markets where accurate positioning is necessary.

The 1575 MHz band is dedicated to GPS/ QZSS /Galileo and brings precise and reliable navigational positioning to urban or rural areas without interruptions. This antenna can pinpoint fixed positions quickly and accurately, especially in built-up areas where buildings may obscure the view to some GPS, including high latitude areas. The 2J7401MGF is the ideal antenna solution for automotive and transportation, including tracking, mapping, and autonomous applications.

For detailed antenna specifications, please see our comprehensive data sheet.

Suggested applications include:

  • Tracking and Mapping
  • Industrial and Agriculture Machinery
  • Sea Vessels
  • Air Navigation
  • Automobile / Transportation
  • Autonomous Vehicles and Machinery

This antenna is designed with a pre-filter that gives an excellent out-of-band rejection while maintaining 28 dB @ 2.7 V GNSS active gain.

Installation / Environmental

The 2J7401MGF antenna measures only Ø 54 × 14.7 mm in size and is ground plane independent. 2J7434MPz comes with a powerful magnetic mount that is strong enough for long-term applications but also offers the convenience of frequent relocation on any metal surface. This low-profile antenna is manufactured with a high-grade PC + ASA UV stable IP67, and IP69K rated enclosure that is anti-corrosive material and is resistant to physical impacts and vandalism making it extremely durable in temperatures ranging between -40C and +85C ideal for outdoor applications. This antenna comes with a standard SMA-Male connector. It is fully customizable with customized connector types, cable lengths, and cable types. 2J7401MGF is manufactured without any hazardous materials and is REACH and RoHS compliant.
