Intellian Sub-Reflector i4

The Intellian Sub-Reflector i4 is a precision parabolic reflector assembly engineered as a replacement component for Intellian i4 and i4P satellite communications systems. This sub-reflector is the critical focusing element that directs and concentrates satellite signals toward the feed horn, making it essential for maintaining peak signal acquisition and data transmission performance on vessels operating in remote waters where reliable maritime communications are non-negotiable.

Marine antenna systems depend on precise reflector geometry to capture weak satellite signals and concentrate them with minimal signal loss. The sub-reflector assembly (part number S2-0334) works in conjunction with the main reflector to create the proper focal point geometry. Over time, salt spray corrosion, UV exposure, and the mechanical stress of vessel motion can degrade reflector surfaces or misalign components, reducing signal strength and causing dropouts during critical communications windows. This OEM replacement restores factory specifications and ensures the antenna maintains its design gain and beamwidth characteristics across the operational frequency band.

This assembly is designed for commercial fishing vessels, offshore research platforms, superyachts, and expedition boats that depend on Intellian i4 systems for weather data, fleet communications, and operational connectivity. The compact form factor (6 × 4 × 7 inches) and lightweight design (0.9 lbs) facilitate installation in tight mast-head environments where space is limited. Operators experiencing signal degradation, acquisition delays, or intermittent lock should verify reflector alignment and condition before assuming system-level failures, as a worn sub-reflector is often the root cause of performance loss in otherwise functional i4 systems.

Note: This product may not be returned to the original point of purchase. For warranty claims or technical concerns, contact Intellian directly. Installation should be performed by qualified technicians familiar with satellite antenna systems to ensure proper alignment and secure mounting.
