The MA131 Hercules antenna is a GPS/GLONASS and ISM Band 915MHz combination 2in1 high performance solution for the most reliable asset tracking and remote monitoring. The integrated metal thread-mount allows for external use on vehicles and outdoor assets worldwide. The 915MHz ISM Band antenna is ideally mounted on a ground-plane but works well also in free-space mounting conditions. The omni-directional gain pattern, with a peak gain of 4dBi when using shorter cable lengths, ensures constant reception and transmission. The GPS/GLONASS antenna has been optimized to work on both GPS and GLONASS bands, allowing the antenna to see the maximum amount of satellites in the sky and improving tracking accuracy enormously especially in built up areas, such as urban canyons where traditional GPS-only solutions struggle to maintain a lock driving around corners. A front-end SAW filter attenuates any nearby out of band wireless transmissions so the GPS LNA is not driven into compression or damaged.
