maruwa sarantel helical connector mount iridium mhf-1621b antenna satellite long range

AMC-ANT-MHF-1621B - Rugged Iridium helical antenna, 45mm high

The AMC-ANT-MHF-1621B rugged Iridium helical antenna from MARUWA uses Sarantel’s distinctive technology. It is a durable elastomeric-plastic over-moulded and dielectric-loaded decafilar-helix antenna which uses MARUWA's distinctive materials technology to provide the highest available efficiency in a small size. The dielectric core together with the fly-wheeling effect of the advanced decafilar helical design provides excellent beam width and low elevation gain, which is maintained in relatively cluttered use scenarios. The AMC-ANT-MHF-1621B acts as its own filter, attenuating signals from common cellular and ISM frequencies by as much as 30dB.


  • Highest available efficiency per unit of volume
  • Excellent beam width and low elevation gain
  • Relatively unimpaired by cluttering objects
  • Designed for harsh environments exposed to force, dust and moisture
  • Base flange groove for O-ring water seal
