Overview

The TOXU TX-G049 is a compact active GNSS antenna designed for integration with compatible multi-band satellite-navigation receivers and positioning equipment.

The antenna covers two specified frequency ranges: 1164–1278MHz and 1525–1615MHz. These ranges support compatible multi-frequency GNSS receiving applications when paired with a receiver operating within the corresponding bands.

The TX-G049 uses right-hand circular polarization to receive compatible circularly polarized satellite-navigation signals. Its specified axial ratio is no more than 1.5dB under the applicable test conditions.

The product information specifies a gain of 35dB. Based on the active antenna configuration, this value is presented as the specified active gain rather than passive antenna-element gain.

With a nominal impedance of 50 ohms and a maximum VSWR of 2.0:1, the TX-G049 is designed for connection to compatible RF and GNSS receiving equipment.

The standard configuration uses an SMA male connector, identified as SMA-J in the supplied drawing. Its direct-connect structure can reduce the need for a separate antenna cable in compatible installations.

The antenna measures approximately 82.8mm in overall length and has a maximum diameter of approximately 40mm. Its compact ABS+PC enclosure and IP67-rated construction support mobile, outdoor, and space-limited equipment installations.

The TX-G049 is an active GNSS antenna only. It receives and amplifies compatible satellite signals but does not independently calculate position, process RTK correction data, or generate navigation output.

• Vehicle Positioning Systems

• Mobile Mapping Equipment

• Precision Agriculture Equipment

• Autonomous Machines and Robots

• Industrial Navigation Terminals

• Surveying and Mapping Equipment

• Outdoor Positioning Devices

System Integration

The TX-G049 must be connected to a compatible GNSS or RTK receiver supporting the required frequency bands.

Because the TX-G049 is an active antenna, the connected receiver must provide compatible DC bias power through the RF port. The required voltage, current, and short-circuit protection should be confirmed before integration because these values are not listed in the supplied product information.

The standard antenna uses an SMA male connector. The connected receiver or cable assembly should therefore provide a compatible SMA female 50-ohm interface.

Before installation, confirm the receiver’s supported frequency bands, antenna-bias capability, input impedance, active-antenna detection function, available mechanical clearance, and connector orientation.

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 signal blockage or electromagnetic interference.

Although the enclosure is specified as IP67, the connector and complete equipment interface must also be correctly assembled and sealed for outdoor use.

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.
