Overview

The TOXU TX-G050 Series is a family of compact multi-band active GNSS helical antennas designed for UAVs, GNSS receivers, RTK equipment, mobile mapping systems, autonomous machines, and other positioning devices.

The series includes multiple mechanical configurations for different installation requirements, including cable-connected cylindrical antennas, low-profile housings, straight or right-angle direct-mount antennas, and flexible gooseneck structures.

Depending on the selected model, the specified frequency coverage extends across compatible GNSS bands within approximately 1154–1621MHz. Each model must be selected according to the receiver’s supported signals, required installation structure, available space, connector configuration, and antenna-bias capability.

The available configurations use an active antenna design with a specified active gain of 38±2dB. The integrated active circuit amplifies received satellite signals before delivering them to a compatible GNSS receiver.

Right-hand circular polarization supports the reception of compatible circularly polarized satellite-navigation signals. The nominal 50-ohm impedance allows integration with common GNSS and RF receiving systems.

The TX-G050 Series comprises receiving antennas only. The antenna receives and amplifies compatible satellite signals but does not independently calculate position, process correction data, or provide RTK positioning accuracy.

Model Selection Guide

Choose TX-G050-503 for Cable-Connected Installation

The compact cylindrical housing and approximately 300mm RF cable support installations where the antenna and receiver port must be separated.

Choose TX-G050-609 for a Wide-Body Low-Profile Structure

The broader enclosure is suitable for equipment requiring a compact antenna height and a larger housing footprint.

Choose TX-G050-501 for Direct Receiver Connection

The straight and right-angle configurations support direct connection to compatible receiver ports with different installation orientations.

Choose TX-G050-502 for Adjustable Orientation

The flexible gooseneck structure allows the antenna body to be repositioned according to the equipment layout and required antenna orientation.

Before selecting a model, confirm the receiver frequency bands, active-antenna bias power, RF connector type and gender, available installation space, cable requirements, and expected operating environment.

System Integration

The TX-G050 Series must be connected to a compatible GNSS or RTK receiver supporting the frequency bands of the selected antenna model.

Because these are active antennas, the connected receiver must provide compatible DC bias power through the RF port. The required operating voltage, current, and protection requirements must be confirmed for the selected configuration before integration.

Connector gender and orientation are model dependent. Do not select a cable or receiver port solely according to the series name. Confirm the final connector drawing or approved sample before placing a volume order.

Install the antenna where it has the clearest practical sky view. Keep it away from large metal obstructions, transmitting antennas, motors, switching power supplies, high-current cables, and other possible sources of electromagnetic interference.

The final RF performance can be affected by the receiver, installation position, surrounding materials, equipment housing, cable loss, power supply quality, and nearby electronics. Sample testing in the actual equipment is recommended before volume production.

For RTK operation, the connected receiver must support RTK processing and receive valid correction data from a base station, NTRIP service, radio modem, cellular modem, or another compatible correction source.

The antenna itself does not generate positioning coordinates or determine positioning accuracy. Final performance depends on the complete GNSS receiver and system configuration.
