Iridium Antenna, UC-1624-341R 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.
Iridium Satellite Network Overview
The Iridium Satellite Network is a low Earth orbit (LEO) satellite constellation that provides voice and data communications across the globe. Unlike terrestrial-based communication systems, Iridium's network consists of 66 active satellites orbiting approximately 485 miles (780 km) above Earth. This design allows for continuous communication coverage even in remote regions, including polar areas, open oceans, and high-altitude environments. The cross-linked nature of the satellites enables global reach without dependence on local ground infrastructure.
UC-1624-341R Iridium Antenna Features
The UC-1624-341R Iridium Antenna is designed to optimize performance with the Iridium satellite system. It features Right-Hand Circular Polarization (RHCP), compatible with the polarization of Iridium satellite transmissions to improve signal stability and reduce loss from reflections and atmospheric effects. The antenna is constructed to handle various environmental conditions, maintaining its performance during temperature shifts, humidity changes, and physical impacts. This makes it suitable for applications in marine and remote terrestrial installations.
Frequency Band and Application
Operating across the Iridium frequency band of 1616 to 1626.5 MHz, the UC-1624-341R supports both voice and data applications. This includes tracking, telemetry, and real-time data communication, ensuring consistent connectivity. The antenna's design focuses on reliable operation in different conditions, which is important for use in maritime vessels, mobile, portable and ground-based stations that require dependable satellite links.
Practical Use Cases
- Marine Operations: The UC-1624-341R is well-suited for maritime vessels, providing reliable voice and data connectivity even in remote ocean regions where traditional cellular networks are unavailable.
- Remote Monitoring: Ideal for oil rigs, remote scientific stations, and field installations requiring constant communication with control centers.
- Disaster Recovery: Provides emergency communication capabilities when terrestrial networks are compromised, ensuring continued coordination during recovery operations.
- Defense and Government Applications: Supports mission-critical communication for military deployments, border patrol operations, and tactical command centers.
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!
Conclusion
The UC-1624-341R Iridium Antenna is designed to enhance the capabilities of the Iridium Satellite Network, providing robust, reliable communication across various industries. Its versatility in installation and practical use cases makes it a solid choice for professionals who require uninterrupted global connectivity.
