Product Description

Overview

The TOXU TX-A94 is a multi-system full-band GNSS active antenna designed for professional surveying, dispatching, and deformation monitoring. It supports GPS, GLONASS, BeiDou, and Galileo across multiple bands (L1/L2/L5; E1/E2/E5a/E5b; B1/B2/B3) and integrates Bluetooth, WiFi, GSM900/1800, WCDMA2100, and 4G for all-in-one connectivity.

Featuring a multi-feed design that minimizes phase center deviation (≤2.0 mm), high passive gain (GNSS ≥5.5 dBi), and a built-in low-noise amplifier (40 ±2 dB, ≤2.0 dB noise figure), the TX-A94 delivers stable satellite reception even in obstructed environments. Its compact 134 × 23.6 mm form factor, ABS waterproof housing, reinforced solder joints, oxygen-free copper wire core, and gold-plated interfaces ensure durable, low-loss performance for industrial deployments.
