Description
The Maxtena M1621HCT-P-SMA is a compact, high-performance passive Iridium antenna, designed for reliable data communication over the Iridium satellite network. It is ideal for use with the RockBLOCK 9704 satellite IoT module.
This rugged antenna features a precision-tuned helical design, providing consistent performance across the full Iridium band (1616–1626.5 MHz). It’s built for durability in challenging environments, with an IP67-rated housing and a low profile form factor that makes it ideal for mobile, maritime, and harsh outdoor deployments.
The M1621HCT-P-SMA connects via a standard SMA male connector and is compatible with a wide range of Iridium-enabled devices, including Ground Control’s RockBLOCK 9704 SMA.
