4G Roof-Mounted Antenna (J-E4RH)


The J-E4RH panel-mounted antenna is designed for permanent installation onto a vehicle roof.

The antenna has been designed to perform even in extreme environments.  At only 82 mm high, and protected by a robust high-impact radome, the antenna is almost impervious to daily wear, tear and impact.

The J-E4RH antenna offers excellent performance across a wide bandwidth, covering all global cellular frequency bands (4G/3G/2G) from 698 MHz up to 2700 MHz.

Support for the 2400 MHz frequency band also allows this antenna to be used as a high-performance Wi-Fi antenna solution.

The antenna is supplied with a convenient adhesive pad and an integrated ultra low loss cable.

Please note that this antenna requires a ground plane, and is therefore only suitable for vehicles with a metal roof – or a non-metallic roof where a ground plane is either already present or is installed with the antenna.  If installing a ground plane this should be at least 25cm in diameter, preferably round, and with the antenna located in the centre.
