This rugged, integrated device combines a high-gain antenna with gateway electronics in a single, easily mounted package.

Gateway Stick combats a common problem with RF networks, which are increasingly used to monitor and control remote devices over tens or hundreds of square miles. Gateways traditionally have different location requirements for their electronics module and antenna, making it necessary to place them separately. Gateway Stick is a revolutionary solution that combines them in one easy-to-install component.
