Overview

The TOXU TX-G036 is a compact, low-profile active GNSS aviation antenna designed for multi-constellation and multi-frequency satellite-signal reception.

It supports compatible GPS L1/L2/L5, GLONASS L1/L2, BDS B1/B2/B3, and Galileo E1/E2/E5a/E5b signals. The antenna can be connected to a suitable multi-band GNSS or RTK receiver for UAV navigation, airborne positioning, mobile mapping, vehicle positioning, robotics, and other professional navigation systems.

The TX-G036 uses right-hand circular polarization and provides a specified antenna gain of at least 3.5dBi at 90° elevation. Its axial ratio is specified as no more than 3dB at 90° elevation, supporting compatible circularly polarized GNSS signal reception.

The integrated low-noise amplifier provides a specified gain of 36±2dB with a noise figure below 1.5dB. The active circuit operates from 3.3V to 18V DC and consumes less than 50mA.

The antenna has a nominal 50-ohm impedance and a VSWR below 2.0:1. Its standard configuration uses a TNC male connector for connection to a compatible RF cable assembly or GNSS receiver interface.

The low-profile housing measures Φ90 × 28.9mm and weighs less than 250g. The flange structure provides three mounting holes for mechanical installation on compatible equipment surfaces.

With IP67 protection, an operating temperature range of -40°C to +75°C, and a storage temperature range of -55°C to +85°C, the TX-G036 is suitable for demanding outdoor and mobile-equipment installations.

The TX-G036 is an active GNSS antenna only. It receives and amplifies compatible satellite signals but does not independently calculate position, process correction data, or provide RTK accuracy.

System Integration

The TX-G036 must be connected to a compatible multi-band GNSS or RTK receiver supporting the required GPS, GLONASS, BDS, and Galileo signals.

The active antenna requires 3.3–18V DC bias power and consumes less than 50mA. Bias power is normally supplied through the RF cable by the connected receiver or a compatible external bias-tee circuit.

Before connection, confirm the receiver’s antenna-bias voltage, available current, supported frequency bands, input impedance, active-antenna detection, and short-circuit protection.

The standard TX-G036 uses a TNC male connector. A compatible TNC female connector and nominal 50-ohm coaxial cable should be used on the mating cable assembly.

Install the antenna horizontally with the upper radome facing the sky. The mounting surface, hole positions, fasteners, mechanical clearance, and waterproof sealing method should be confirmed against the approved drawing before installation.

For optimum reception, provide the clearest practical sky view and keep the antenna away from large metal obstructions, transmitting antennas, motors, switching power supplies, high-current cables, and other potential sources of reflection or electromagnetic interference.

The IP67 rating applies to the antenna enclosure under the specified product configuration. The mating connector, cable joint, mounting holes, and complete equipment installation must also be correctly sealed.

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 source.
