  • Overview
  • Tech Specs
  • Documentation
  • A single solution to connect your smart devices to the Cloud. The antenna supports the GSM 850 / 900 / 1800 / 1900 MHz and UMTS bands. Designed for small devices, this antenna will work when used as wireless terminal, gateway, or access point. It is a ground plane independent design, housed in a robust waterproof plastic cover. It can be used outdoors in any kind of telemetry project, as well as for discreet in-vehicle installations. It comes with a high grade adhesive tape that allows the antenna to be attached to any surface. Please note, the antenna is not meant to be mounted on large metallic surfaces, since it would affect the antenna’s coverage. It works great on other materials such as glass, plastic, wood, or cardboard.
