Introduction 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. The Hercules is also prized by the leading wireless device brands globally due to its unique mechanical construction. The compact size and rugged polycarbonate construction, which can withstand direct attack and hazards such as tree-branches, coupled with a waterproof rating of IP67 and IP69K (waterproof against high pressure industrial cleaning from top and bottom sides) are un-matched in the industry. The standard cable length and connector option is 200mm RG316 and SMA(M). The cable length and connector are customizable. Taoglas supplies low loss extension cables according to your requirement. Maximum cable length should not go beyond 5 meters in order to maintain adequate antenna performance. The Hercules is also available in White.
