Product Introduction
1. Ultra-Small Design, Easy Integration
Measuring only 50mm × 50mm × 17mm, the antenna is one of the most compact Iridium antennas on the market. This miniaturization allows for easy integration into a variety of portable devices, trackers, and IoT hardware, eliminating the need for a large antenna footprint.
2. Passive Design, Plug-and-Play
As a passive antenna, it requires no external power supply. It comes standard with a 3-meter coaxial cable and a standard SMA female connector. Users simply connect it to a compatible Iridium module or terminal to establish a satellite link, enabling rapid deployment.
3. Precision Tuning for Optimized Signal Reception
The antenna is precisely tuned to the Iridium system's downlink frequency (1621MHz ±5MHz) and utilizes right-hand circular polarization (RHCP). This perfectly matches the polarization characteristics of Iridium satellite signals, enabling efficient reception of signals from mobile satellites and improving connection stability.
4. Rugged and durable for harsh environments
With an operating temperature range of -30°C to +85°C, it can withstand extreme temperatures from freezing to scorching, ensuring stable operation in harsh environments such as the field, at sea, and onboard vehicles, meeting the high reliability requirements of outdoor and industrial applications.
5. High Compatibility and Easier Replacement
The standard SMA interface and 50-ohm impedance make it directly compatible with a variety of Iridium communication modules on the market, such as RockBLOCK and Iridium 9602/9603. This makes it easy to integrate into new products or replace the original antenna of existing equipment.
Application Scenarios
Emergency Communications Equipment: Integrates into personal emergency beacons (PLBs) and satellite text messaging terminals to provide lifeline communications in areas without terrestrial networks.
Global Asset Tracking: Used for global satellite tracking and monitoring of cross-border assets such as ocean containers, cold chain logistics, and heavy equipment.
Maritime Applications: Provides satellite data connectivity for small vessels, buoys, and ocean observation equipment.
Field Data Collection: Deployed at remote energy, mining, agricultural, or scientific research sites, it automatically transmits monitoring data back via the Iridium network.
Portable Military/Government Terminal: Integrates into portable military personnel equipment or government field equipment requiring global satellite communications.
FAQ
Q: Is this antenna active or passive?
A: It is a passive antenna, meaning it does not require an external power source to operate.
Q: Does it support full Iridium voice and data services?
A: It is an antenna that receives and transmits signals. To use Iridium voice or data services, you must connect it to a compatible Iridium module or satellite phone terminal.
Q: Can the cable length be customized?
A: The standard product comes with a 3-meter cable. For bulk orders, the cable length can usually be customized by contacting customer service.
Q: Its gain is 0dB. Is this sufficient performance?
A: 0dB gain is typical for such a small passive antenna. It provides an omnidirectional radiation pattern, making it ideal for applications requiring connectivity to satellites in all directions, such as from a moving vehicle or vessel.
Q: What is the operating temperature range of the antenna?
A: The antenna operates in ambient temperatures ranging from -30°C to +85°C.
Q: What type of connector does it use?
A: It uses a standard SMA (female) connector, which is common on many wireless communication modules.
