SI-TEX Professional Dual Range Radar w/6kW 4.5 Open Array – 10.4 Color TFT LCD Display

Description

Set up professional dual-range radar coverage where space is tighter with the SI-TEX T-2021-4.5, a 6 kW magnetron radar using a 4.5-foot open array. Its 1.7° horizontal beam gives operators useful bearing definition without requiring the full rotation space of a 6-foot antenna, making it a practical fit for many commercial fishing boats, workboats, and offshore cruisers. Need direct range and bearing measurements from a dedicated radar display? This system includes a 10.4-inch color TFT screen with Variable Range Marker and Electronic Bearing Line functions for compatible navigation workflows.

Integration

The package includes a dedicated radar display for primary radar operation. External position, heading, speed, and AIS information may be needed for certain display modes, overlays, target functions, and vessel-data features. Confirm available NMEA interfaces and sensor compatibility before planning an integrated navigation installation.

VRM and EBL functions help operators estimate distance and bearing from the radar display, but radar results must be interpreted alongside visual observation, current charts, navigation instruments, and safe operating procedures. The 64 NM range is instrumented; actual performance depends on conditions and installation.

Installation Notes

Install the 4.5-foot scanner on a level, reinforced platform with unrestricted rotation clearance. Avoid shadowing from masts, rigging, hardtops, antennas, lights, exhaust, and other structures. Mount the display where it can be viewed and operated safely at the helm.

Use properly protected 12V or 24V DC power, marine-grade wiring, and secure cable routing away from heat, standing water, sharp edges, and high-current conductors. Follow SI-TEX instructions for safe distances, grounding, scanner alignment, and operational checks.

Before Ordering

Verify 4.5-foot array clearance, radar-mount capacity, display location, 12V/24V power availability, cable lengths, external sensor needs, and the availability of qualified installation support before ordering.
