4G, 2.4/5 GHz Wi-Fi (MIMO) & GPS Roof-Mounted Antenna (J-E4xRL)

The J-E4xRL range of low-profile antennas is capable of supporting up to four high performance antenna elements all within a single housing:

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

The J-E4xRL is available in a range of configurations, with all antenna elements (up to 4) located in a single robust and compact housing.

Designed to be tough yet cost effective, the antennas are completely enclosed in a moulded housing made from weather and impact resistant plastic.

The J-E4xRL series does not require a ground plane, making it suitable for installation onto all roof types.
