Introduction

Monitors purchased before May 2020 were fitted with a Wi-Fi/GSM cellular antenna. However, if you need a 4G/LTE connection, you can replace that antenna with a LTE/GPS antenna using an upgrade antenna kit. The replacement antenna forgoes Wi-Fi but adds GPS capability. If required, you can maintain Wi-Fi by adding an internal Wi-Fi antenna to the monitor’s embedded PC.

  1. The monitor has a built-in cellular antenna on the outside roof of the enclosure (right side).
