DM-1620 (Iridium®)

Iridium Surface-Mount Antenna


The DM-1620 is a compact RHCP antenna for Iridium communications on vehicles, containers, and equipment housings.

  • Operates across the 1616–1626.5 MHz Iridium band with 3.5 dBi peak gain.
  • Uses a 3-inch ASA dome with a gasketed stud mount for exposed installations.
  • Includes 10 ft of LL-195 cable terminated with an SMA plug.

Customization: Cable type, cable length, and connectors can be configured for specific installation requirements.

Product Description

The DM-1620 provides a low-profile Iridium connection for mobile and fixed equipment. Its right-hand circularly polarized element covers 1616–1626.5 MHz, matching the polarization used for Iridium communications.

A UV-resistant ASA dome and sealing gasket protect the antenna at the mounting surface. The 5/8-inch feed-through supports installation on vehicles, containers, fiberglass housings, and other equipment panels.

Ideal applications:

  • Vehicle and equipment tracking
  • Iridium communications terminals

Example Model Configurations: DM-1620-3C-WHT-120
