SparkFun Iridium Qualified 9704 Helical Antenna: Rugged, High-Performance Satellite Antenna

The SparkFun Iridium Qualified 9704 Helical Antenna (Maxtena M1621HCT-P-SMA) is a compact, precision-tuned passive antenna engineered for reliable communication across the Iridium satellite network. Designed for compatibility with the RockBLOCK 9704 SMA module and other Iridium-enabled devices, this antenna ensures consistent performance across the full Iridium frequency band (1616–1626.5 MHz).

Its helical design delivers stable performance, with a typical peak gain of 2.8 dBic, excellent axial ratio (0.2 dB typical), and 50-ohm impedance for optimal matching. Housed in a rugged, IP67-rated enclosure, the antenna is built for harsh outdoor and maritime environments, withstanding temperatures from -40C to +85C. The compact size (49mm × 19mm) and low-profile form factor make it ideal for mobile and space-constrained deployments.With its SMA male connector, the antenna is easy to integrate into a wide range of satellite IoT projects requiring reliable, global Iridium connectivity.
