Overview

The TOXU TX-G014 is a compact four-arm helical active GNSS antenna designed for single-frequency satellite navigation equipment operating across the 1559–1602MHz range.

This frequency range covers compatible GPS L1, BDS B1, and GLONASS L1 satellite navigation signals. Actual constellation and positioning support depend on the capabilities of the connected GNSS receiver.

The antenna adopts a four-arm helical structure with right-hand circular polarization. This design supports GNSS signal reception in mobile equipment where the antenna may not always remain in a fixed horizontal orientation.

At 90° elevation, the antenna has a specified gain of at least 2dBi and an axial ratio of no more than 3dB.

The integrated low-noise amplifier provides 36±2dB gain with a specified noise figure below 2.0dB. The active circuit operates from 3.3–18V DC with current consumption below 30mA.

The TX-G014 uses a nominal 50-ohm RF interface and an SMA male connector. Its compact Φ18 × 70mm housing weighs less than 20g, supporting integration into UAVs, handheld terminals, tracking devices, navigation equipment, and other weight-sensitive platforms.

The specified enclosure protection rating is IP67. Final environmental protection still depends on the mating connector, installation interface, equipment enclosure, and complete system assembly.

The TX-G014 is a GNSS antenna only. It does not contain a GNSS receiver, RTK engine, navigation processor, inertial measurement unit, correction-data modem, or positioning-data output interface.

Key Features

Four-Arm Helical Structure

The helical antenna structure supports circularly polarized GNSS reception in mobile equipment where antenna orientation may change.

1559–1602MHz Frequency Coverage

Covers compatible GPS L1, BDS B1, and GLONASS L1 satellite navigation signals.

Right-Hand Circular Polarization

RHCP polarization supports reception of compatible GNSS satellite signals.

≥2dBi Gain at 90° Elevation

The antenna element provides a specified gain of at least 2dBi in the zenith direction.

≤3dB Axial Ratio at 90° Elevation

The specified zenith axial ratio supports circularly polarized signal reception.

36±2dB Integrated LNA

The built-in active circuit amplifies received GNSS signals before transferring them to the connected receiver.

Noise Figure Below 2.0dB

The specified low-noise amplifier limits additional noise introduced during signal amplification.

Wide 3.3–18V DC Bias Input

The active antenna supports receiver-supplied bias power across a wide voltage range.

Current Consumption Below 30mA

The specified current consumption supports integration into compatible mobile and battery-powered equipment.

Compact Φ18 × 70mm Housing

The cylindrical structure supports installation in equipment with limited antenna space.

Weight Below 20g

The lightweight configuration is suitable for UAVs, handheld terminals, and other weight-sensitive devices.

SMA Male Connector

The standard configuration connects to a compatible SMA female receiver or RF interface.

IP67 Enclosure Rating

The specified enclosure rating supports installation in equipment exposed to dust and temporary water ingress, subject to correct system-level installation.

Applications

• Unmanned Aerial Vehicles

• Handheld GNSS Terminals

• GPS and GNSS Tracking Devices

• Mobile Navigation Equipment

• Remote Telemetry Systems

• Navigation and Dispatch Equipment

• Monitoring and Control Devices

• Portable Measurement Equipment

• GPS L1 Receiver Systems

System Integration

The TX-G014 must be connected to a compatible GNSS receiver supporting the required GPS L1, BDS B1, or GLONASS L1 signals.

The active antenna requires 3.3–18V DC bias power, normally supplied through the RF connector by the connected receiver. Confirm the receiver’s antenna-bias voltage, current capacity, short-circuit protection, and active-antenna detection functions before connection.

The SMA male connector must be connected to a compatible SMA female interface. Connector gender, polarity, and thread type must be confirmed before quotation and production.

The antenna cannot add unsupported satellite signals to the receiver. For example, BDS or GLONASS reception requires both antenna frequency compatibility and a receiver capable of processing the corresponding signals.

The TX-G014 is a single-frequency L1-region antenna. It must not be represented as an L1/L2/L5 multi-frequency RTK antenna.

It may be integrated into a positioning system using an L1-capable receiver, but the antenna itself does not calculate positions or process RTK correction data.

For UAV and mobile-equipment installation, position the antenna away from high-power transmitters, switching power supplies, motors, digital clock sources, metal obstructions, and other potential electromagnetic interference sources.

Final RF and positioning performance should be tested on the customer’s finished equipment because the installation position, surrounding structure, receiver, power supply, connector, and RF environment can affect signal reception.

FAQ

Q: What type of antenna is the TX-G014?

A: It is a four-arm helical active GNSS antenna covering 1559–1602MHz.

Q: Which satellite navigation signals does it support?

A: Its specified frequency range covers compatible GPS L1, BDS B1, and GLONASS L1 signals.

Q: Does it support GPS L2 or L5?

A: No. The TX-G014 is specified for 1559–1602MHz and should not be marketed as an L1/L2/L5 multi-frequency antenna.

Q: Is it an active antenna?

A: Yes. It integrates a low-noise amplifier with 36±2dB specified gain.

Q: What bias voltage is required?

A: The active circuit operates from 3.3–18V DC with current consumption below 30mA.

Q: Which connector does it use?

A: The standard configuration uses an SMA male connector.

Q: Can it be connected directly to an SMA female receiver port?

A: Yes, provided the receiver port uses a compatible standard SMA female interface and supplies the required active-antenna bias power.

Q: Can this antenna be used for RTK?

> A: It may be evaluated with a compatible L1-capable positioning receiver, but it is not a multi-frequency RTK antenna and does not independently calculate RTK positions.

Q: Is the antenna waterproof?

A: The antenna enclosure is specified as IP67. Final waterproof performance depends on the connector, mating interface, installation method, and complete equipment enclosure.

Q: Is it suitable for UAVs?

A: Its four-arm helical structure, compact Φ18 × 70mm housing, and weight below 20g support evaluation in UAV applications. Final RF performance must be verified on the complete UAV platform.

Q: Can TOXU customize the product?

A: Connector configuration, housing, marking, label, and packaging can be evaluated according to project requirements.
