PRE OWNED FURUNO FBB-250 FURUNO FBB-250 DOM MARINE ANTENA

PRODUCT OVERVIEW

The FBB-250 dome is a 3-axis stabilized tracking antenna designed to provide uninterrupted broadband connectivity over the Inmarsat I-4 satellite network. It is the standard solution for vessels that require faster data than the 150-series (up to 284 kbps) but do not have the space or budget for the larger 500-series domes.

Equipped with high-precision rate sensors and brushless motors, the FBB-250 antenna maintains a constant satellite lock despite the vessel’s rolling, pitching, or high-speed maneuvers. It supports simultaneous high-quality voice calls and standard IP data, making it the primary choice for modern fleet management, electronic chart updates (ENC), and crew welfare.

KEY FEATURES & APPLICATIONS

-- Balanced Performance: Delivers significantly higher data speeds than Mini-C or FBB-150 units while remaining small enough for easy installation on masts of all sizes.

-- Advanced Tracking: The internal mechanical stabilization system uses GPS and motion sensors to ensure zero signal loss in sea states with extreme motion.

-- Global Office Capability: Supports VPN, encrypted email, and multi-user web browsing, allowing the ship to function as a remote office anywhere in the world.

-- Simultaneous Service: Enables the use of a telephone handset while data is being transmitted, ensuring the bridge is never cut off from voice communication.

-- Low Maintenance: Built with a high-impact radome that protects the internal RF electronics from UV radiation, salt-water ingress, and heavy vibration.

-- Easy Retrofit: Often shares similar mounting patterns with older Inmarsat systems, making it a popular choice for refurbished upgrades in the Bhavnagar market.

TYPICAL CONDITION (USED/REFURBISHED)

Sourcing an FBB-250 dome from Alang/Bhavnagar ship-recycling yards is a common practice for vessel operators looking for cost-effective spares. Refurbished units undergo a strict "tracking test" to ensure the motors are silent and responsive. We verify that the LNA (Low Noise Amplifier) provides the correct gain for Inmarsat-C/FBB reception and check the radome for any structural fatigue or seal degradation.
