Description

Bring professional-grade long-range radar coverage to a working vessel or offshore boat with the SI-TEX T-2041-4.5 dual-range radar system. Its 12 kW magnetron transmitter and 4.5-foot open array provide a 1.7° horizontal beam for separating traffic, structure, and shoreline returns during night passages, commercial operations, or changing-weather runs. Need to watch close-in activity and distant returns at the same time? This complete system combines a 10.4-inch color TFT display, dual-range presentation, real-time head-up mode, and ATA target tracking.

Integration

This package includes a dedicated radar display and does not require an MFD for fundamental radar operation. ATA, heading-up presentation, AIS overlay, true trails, and other navigation-related functions may require compatible external GPS, heading, speed, or AIS inputs, depending on the selected feature.

The 72 NM value is an instrumented range, not a guarantee that every object will be detected at that distance. Scanner height, target size, radar settings, precipitation, sea clutter, vessel motion, nearby structures, and installation quality all affect real-world results.

Installation Notes

Mount the 4.5-foot open array on a rigid, level platform that can carry the scanner, gearbox, rotational load, and anticipated wind load. Allow full antenna sweep clearance and avoid placing the scanner near people, masts, antennas, rigging, lights, exhaust, or structures that can create shadow sectors.

Use properly sized power cables, correct overcurrent protection, and protected routing for scanner and display connections. Follow SI-TEX installation guidance for safe operating distances, mounting hardware, grounding, and bearing alignment. Radar is a navigation aid and does not replace a proper lookout, safe speed, charts, or navigation-rule compliance.

Before Ordering

Confirm display mounting space, 12V/24V/32V DC power compatibility, available cable routes, 4.5-foot sweep clearance, mounting-platform strength, heading/GPS sensor needs, and qualified installation support before ordering.
