Xtreme-Radiator - Indoor GPS Re-Radiator

30 Metre Range, External Screw Mount, Internal Suction Mount, AC Power


The Xtreme-Radiator is an enhanced version of the best-selling Super-Radiator with a wider radiating range of 30 meters. This excellent GPS L1 band signal repeating antenna features dual antennas to re-transmit real-time GPS satellite outdoor receptions to an indoor environment.

Designed to operate as a whole, the system kits are composed of a highly sensitive external GPS antenna, precisely calibrated amplifier circuit with Helix type indoor repeating antenna and a built-in power supply regulator. The Helix type indoor antenna system allows multiple GPS receiver users to perform on-the-fly normal receiver operation within a closed environment, while the main GPS antenna is installed on an unmanned location outdoors.

The Xtreme-Radiator is most commonly used in laboratories and in underground garages or other buildings requiring a GPS signal indoors. A common application is in firehalls where the Xtreme-Radiator supplies a GPS signal to the fire trucks while they are in the garage, reducing response time when the trucks are needed
