Active Inmarsat Antenna Bundle - 1550MHz
The Active Inmarsat Antenna Bundle - 1550MHz is a professional-grade satellite communication antenna system designed for receiving L-band signals from Inmarsat satellites operating at 1550MHz frequency. This bundle is extensively used by maritime operators, aviation professionals, emergency response teams, and remote communication specialists who require reliable global satellite connectivity in areas without terrestrial network coverage. The active antenna configuration with integrated low-noise amplifier solves the critical challenge of weak signal reception in remote locations by providing gain amplification and noise figure optimization for clear, uninterrupted satellite data transmission.
Product Overview
The Active Inmarsat Antenna Bundle operates on the principle of directional RF reception coupled with active signal conditioning. The antenna element captures L-band signals from Inmarsat satellites, which are then routed through a pre-amplifier stage that provides approximately 30-40dB of gain while maintaining a low noise figure typically below 2dB. This ensures that weak satellite signals are amplified before reaching the receiver, significantly improving signal-to-noise ratio and data integrity. The 1550MHz frequency band is specifically allocated for Inmarsat satellite downlink communications, making this antenna essential for maritime safety systems, aircraft emergency communications, and global mobile personal communications by satellite (GMPCS) applications.
What distinguishes this bundle is the integration of weatherproof radome protection, impedance-matched connectors, and a compact form factor suitable for installation on vessels, aircraft, and mobile platforms. The active amplification stage is powered via coaxial cable, eliminating the need for separate power infrastructure at the antenna location. The bundle typically includes the antenna element, integrated LNA module, mounting hardware, weatherproof connectors, and installation documentation. This complete package ensures minimal signal loss over cable runs and provides plug-and-play compatibility with standard satellite communication receivers operating in the L-band frequency range.

- Aviation Emergency Communications: Integration with aircraft Emergency Locator Transmitters (ELTs) and Satellite Emergency Position Indicating Radio Beacons (EPIRBs) for global coverage in remote oceanic regions beyond terrestrial radar and VHF range
- Remote Field Operations: Deployment in oil and gas exploration sites, mining operations, and geological survey expeditions where terrestrial networks are unavailable, requiring reliable satellite data links for operational coordination
- Disaster Response and Emergency Management: Rapid deployment in flood, earthquake, and humanitarian crisis zones for establishing communication infrastructure when conventional networks are compromised or destroyed
- Scientific Research Expeditions: Support for polar research stations, deep-sea oceanographic vessels, and remote laboratory installations requiring continuous data transmission to shore-based facilities
How to Use
Begin installation by selecting an optimal mounting location with unobstructed sky view, preferably on a vessel's mast, aircraft external mounting point, or elevated platform. Ensure the antenna is oriented vertically or at the angle specified in the installation documentation for maximum signal reception. Securely fasten the antenna using the provided stainless steel mounting brackets, ensuring weatherproof sealing around cable entry points. Connect the coaxial cable to your satellite communication receiver, ensuring proper impedance matching and connector compatibility. If your receiver lacks integrated Bias-T capability, install an external Bias-T injector unit between the antenna and receiver to supply the required 12-18VDC power to the integrated amplifier stage.
Before operational deployment, verify power supply voltage at the antenna connector using a multimeter to confirm proper Bias-T function. Perform a signal strength test by monitoring the receiver's signal quality indicator while the antenna is properly oriented toward the satellite footprint. Adjust antenna position incrementally if initial signal levels are suboptimal. Establish baseline signal measurements under clear sky conditions for future reference and troubleshooting. Regularly inspect the radome for physical damage, salt spray accumulation (in marine environments), or UV degradation. Clean the radome surface with fresh water and mild detergent annually to maintain optimal RF transparency and prevent signal attenuation from environmental contamination.
Frequently Asked Questions
What is the difference between active and passive Inmarsat antennas?
Passive antennas rely solely on the antenna element to capture signals, requiring the receiver to have a sensitive low-noise amplifier stage. Active antennas integrate the amplifier at the antenna location, providing signal amplification before transmission through the coaxial cable. This reduces cable loss impact, improves overall system noise figure, and allows longer cable runs without signal degradation. Active antennas are preferred for maritime and aviation applications where cable runs exceed 10 meters or signal conditions are marginal.
Can this antenna be used with non-Inmarsat satellite systems?
While this antenna is specifically tuned for the 1550MHz Inmarsat L-band frequency, it may provide reception for other satellite systems operating within the 1525-1575MHz L-band range, such as certain Iridium backup services or maritime safety systems. However, optimal performance is guaranteed only for Inmarsat satellites. For other systems, consult the satellite operator's frequency specifications and verify compatibility with your receiver before deployment.
What power supply voltage should be used for the integrated amplifier?
The standard power supply range is 12-18VDC, with 15VDC being the nominal operating voltage. Current consumption is typically 50-100mA depending on the specific amplifier design. The power is delivered via a Bias-T injector that combines the DC voltage with the RF signal on the same coaxial cable. Ensure your power supply can deliver stable voltage without ripple exceeding 0.5V, as voltage fluctuations may degrade amplifier performance and introduce noise into the received signal.
How do I verify proper antenna orientation for maximum signal reception?
Inmarsat satellites are in geostationary orbit, appearing stationary in the sky relative to a fixed ground location. Use online Inmarsat coverage maps or mobile applications to determine the satellite's azimuth and elevation angle from your installation location. Point the antenna toward these coordinates, ensuring the radome faces the satellite direction without obstruction from masts, structures, or terrain. Monitor the receiver's signal quality indicator while making fine adjustments. Peak signal levels typically occur when the antenna is pointed directly at the satellite sub-point within your coverage area.
