The patented HC600E embedded passive helical antenna is designed to enhance the signal-to-noise ratio of communications over voice and data modems on the Iridium® frequency band (1616.0 – 1626.5 MHz)


  • Gain over full bandwidth (3.7 dBic)
  • Excellent axial ratio (≤ 0.5 dB at zenith)
  • ESD circuit protection (15 kV)
  • REACH and RoHS compliant


  • Extremely light (4 g)
  • Excellent RH circular polarized signal reception
  • Increased system accuracy
  • Excellent signal-to-noise ratio
  • Industrial temperature range
  • Remote SBD antenna


Weighing only 4 g, the light and compact HC600E features a precision-tuned helix element that provides excellent axial ratios and operates without the requirement of a ground plane, making it ideal for a wide variety of applications, including unmanned aerial vehicles (UAVs) and Iridium® voice and data applications.

Calian provides an optional embedded helical mounting ring (P/N 23-0219-0), which traps the outer edge of the antenna circuit board to the host circuit board or to any flat surface. Calian also provides support for installation and integration of embedded helical antennas to enable the integrator to achieve a successful installation and obtain optimum antenna performance.
