4G (MIMO), 2.4/5 GHz Wi-Fi (MIMO) & GPS Shark Fin Antenna (J-S4Dx)

Overview

The J-S4Dx has a compact, OEM style shark fin housing which supports up to five high performance antenna elements:

  • Two ultra-wideband elements support MIMO operation at cellular frequencies (4G/3G/2G)
  • Two dual-band elements support MIMO operation for 2.4 & 5 GHz Wi-Fi
  • A high performance active GPS/GLONASS/Galileo/Beidou antenna

The J-S4Dx is available in a range of configurations, with all antenna elements (up to 5) located in a single rugged enclosure.  If specified with all 5 antenna elements the J-S4Dx offers a complete all-in-one MIMO antenna solution for our PCs or routers.  

The J-S4Dx series does not require a ground plane, making it suitable for installation onto all roof types.
