4G (MIMO), 2.4/5 GHz Wi-Fi (MIMO) & GPS Roof-Mounted Antenna (J-E4Dx)

Overview

The J-E4Dx range of antennas is capable of supporting up to six isolated high performance antenna elements all within a single housing:

  • Two ultra-wideband elements support MIMO operation at cellular frequencies
  • Two or three dual-band elements support MIMO operation for 2.4 & 5 GHz Wi-Fi
  • A high performance active GPS antenna

The J-E4Dx is available in a range of configurations, with all antenna elements (up to 6) located in a single rugged enclosure.  If specified with 5 or 6 antenna elements the J-E4Dx offers a complete all-in-one MIMO antenna solution for our PCs or routers.  

The J-E4Dx series does not require a ground plane, making it suitable for installation onto all roof types.  

The J-E4Dx series of antennas is also available with a white enclosure instead of black.

Please note that due to the number of internal antennas the J-E4Dx has a relatively large diameter, which may not be obvious from the picture - dimensions can be viewed below.
