Overview

The TOXU TX-G052 is a compact multi-band active GNSS quadrifilar helical antenna designed for UAVs, micro RTK receivers, handheld positioning terminals, tablets, portable data-collection equipment, and other satellite-navigation devices requiring a lightweight external antenna.

The antenna covers two specified working frequency ranges: 1164–1230MHz and 1560–1610MHz. It is intended for use with compatible GNSS receivers operating within these frequency ranges.

The TX-G052 adopts a quadrifilar helical architecture and right-hand circular polarization. Its four-arm helical structure provides a compact cylindrical antenna form suitable for equipment where installation space and antenna weight are limited.

An integrated low-noise active circuit provides a specified gain of 40±2dB typical. The specified maximum noise figure is 1.5dB, helping amplify received satellite signals before delivering them to the connected GNSS receiver.

The flexible gooseneck section allows the antenna body to be repositioned according to the receiver-port orientation, surrounding equipment structure, and available installation space.

The TX-G052 operates from 2.8–5V DC and has a specified current consumption of 26±2mA at 3.3V. Power is normally supplied by a compatible GNSS receiver through the RF connector.

The antenna has a nominal impedance of 50 ohms and uses an SMA male connector. Its approximate overall dimensions are Φ28 × 160mm, and its weight is no more than 18g.

The TX-G052 is an active receiving antenna only. It does not independently calculate coordinates, process RTK correction data, or determine positioning accuracy. These functions must be provided by the connected GNSS or RTK receiver.

System Integration

The TX-G052 must be connected to a compatible GNSS or RTK receiver supporting the required operating frequencies within 1164–1230MHz and 1560–1610MHz.

Because the TX-G052 is an active antenna, the connected receiver must provide compatible DC bias power through the RF port. The receiver should support the specified 2.8–5V DC operating range and provide sufficient current for the antenna.

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

Before integration, confirm the receiver’s supported GNSS frequencies, antenna-bias voltage, available current, RF input impedance, connector gender, mechanical clearance, and installation orientation.

The flexible gooseneck supports antenna-angle adjustment, but repeated excessive bending or sharp folding should be avoided to reduce the risk of mechanical or internal RF damage.

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

Final system performance can be affected by the GNSS receiver, installation orientation, surrounding materials, equipment housing, power-supply quality, nearby electronics, and operating environment. Testing with the actual receiver and complete equipment is recommended before volume production.

For RTK applications, 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 receives and amplifies compatible satellite signals but does not independently generate positioning coordinates or determine positioning accuracy.
