Iridium Block 1 Antenna – External Overmoulded- SMA Connector

Part of the Iridium Block 1 series of DielectriX™ antennas from Helix Geospace which are highly resilient, ruggedised designed and developed for hand-held and other products where size and performance are critical.

The DC2-11P1S2-0 is a high-performance antenna created for the Iridium network built upon DielectriX technology. Helix’s Iridium antennas feature exceptional multi-path (reflected) signal selectivity and are resistant to RF and electrical noise. They’re balanced and isolated from platform ground, so they’re resilient to common-mode noise. They’re also unaffected by nearfield object de-tuning. Satelles STL (Satellite Time and Location) services, which are utilised for GPS backup, are also supported by the antenna.

Helix Geospace Iridium Block 1 series antennas are ideally suited for Iridium applications in which resilience and compact form factor are essential:

  • All Iridium voice and SBD (Short Burst Data) applications – satphones and terminals
  • Satelles STL service applications
  • Defence/security/CNI/first responder
  • Asset tracking and fleet vehicle tracking
  • Internet of Things
  • Personal safety devices
  • Hand-held and wearable devices
  • Autonomous vehicles and drones
  • Industrial/Oil & gas/Mining
