The M1600HCT-P-SMA is unique antenna combining the ability to communicate with the Iridium satellite network while simultaneously receiving L1 GNSS signals（GPS and GLONASS）. This makes the M1600HCT the perfect antenna for tracking devices that transmit their position over Iridium. In addition, weighing only 11 grams, the antenna can achieve IP67 when seated against an SMA bulkhead connection（there is a small o-ring built into the base）.
This product is designed for applications requiring high quality reception of the Iridium network and is ideal when：the orientation of the unit containing the antenna is random, the unit is used in harsh environments, and/or the antenna is mounted externally and in close proximity to other antennas.
