Overview

The GNSS-L1256-40TNC is a high-performance, active dome antenna designed for multi-constellation GNSS reception across the L1, L2, L5, and L6 bands. It features a high-gain 40dB low-noise amplifier (LNA) and advanced out-of-band filtering to ensure reliable positioning in RF-congested environments. This ruggedized antenna is MIL-STD-810G certified and IP67 rated, making it suitable for harsh military and industrial deployments.

Why Choose This Part

This antenna offers a wide operating voltage range of 2.5V to 12V and high 40dB typical gain, ideal for long cable runs where signal loss is a concern. Its IP67-rated dome housing provides superior multipath mitigation and environmental protection for permanent outdoor installations.

Applications

Precision Agriculture
Provides the high-gain signal reception necessary for centimeter-level accuracy in automated tractor steering and crop mapping.
Positive Train Control (PTC)
AAR compliant design for rolling stock tracking and safety-critical rail synchronization.
