UC-1624-341R Data

Iridium Antenna description

The UC-1624-341R is a Quadrifilar Helix Iridium Antenna with dimensions 4 cm/1.5" OD x 11 cm/4.5" H. It is designed for use with L-band (1.6 GHz) Iridium modems and radios. The Iridium network the UC-1624-341R is designed for, consists of a meshed constellation of low earth orbiting satellites (LEO satellites). The constellation is large, enabling real-time, worldwide communications, even in remote locations lacking of a radio infrastructure. Iridium is often the more economical means of real-time communications at sea, in a desert, or in the wilderness. In Asia, Africa, Oceania and Europe, the Thuraya satellite network is a close contender. For more information on Thuraya, go to our UC-1614-341L Thuraya Antenna model)

For embedded and weight sensitive applications, such as self-buoyant air and water platforms, like balloons and buoys, we offer a 30 gram (1 oz) lightweight version: UL-1624-341R-LIGHT (select from above Base/Flange drop down menu). It is enclosed in a light housing, measuring 27.5 mm (1.08") OD x 99 mm (3.9") L, with an SMA Female connector at its bottom center.

Netted Iridium compatibility

The UC-1624-341R Iridium Antenna is compatible with Distributed Tactical Communications System (DTCS), Netted Iridium applications. These enable group communications within an Iridium satellite's spot beam.

The UC-1624-341R is broadband enough that it can be used to receive GPS (Global Positioning System) and Iridium signals simultaneously. The connected radios must support this dual capability, such as a DTCS-RO Iridium Handset.

UC-1624-341R Navigation Network compatibilities

Although the antenna is optimized for Iridium operation, its bandwidth will also support operation within the following Navigation Networks: GPS L1 (USA), GLONASS L1 (RF), Galileo E1 (EU), Beidou/Compass B1/E1/E2 (CN). This means that you can use one antenna for both Iridium communications and Navigation!
