Overview

The TOXU TX-G98 is a 5-in-1 external combination antenna integrating one active GNSS antenna, two independent cellular antenna elements, and two independent WiFi/Bluetooth antenna elements into one compact mushroom-style housing.

The active GNSS section supports GPS L1 at 1575.42MHz and BDS B1 at 1561.098MHz. It provides 28±3dB active gain, a noise figure of ≤1.5dB, and requires a compatible 3-5V DC bias supply through the GNSS coaxial cable.

The two passive LTE antenna elements cover 824-960MHz and 1710-2690MHz, providing separate RF signal paths for the main and auxiliary antenna ports of compatible 4G LTE MIMO communication equipment.

Two additional passive WiFi/Bluetooth antenna elements provide independent wireless connections. According to the available specifications, one antenna path covers 2400-2500MHz, while the other supports 2.4-5.8GHz.

By integrating satellite positioning, cellular communication, and wireless data connectivity into one housing, the TX-G98 helps reduce the number of separately installed antennas required by vehicle telematics units, IoT gateways, tracking equipment, industrial terminals, and mobile communication systems.

The standard configuration uses five 1000mm RG174 coaxial cables with SMA male connectors. Cable type, cable length, connector series, connector gender, cable labels, and port assignments can be customized according to the customer’s equipment interface.

System Integration

The TX-G98 provides five independent RF connections: one active GNSS connection, two LTE connections, and two WiFi/Bluetooth connections.

The two LTE cables should be connected to the corresponding main and auxiliary antenna ports of a compatible 4G LTE MIMO communication module. Both LTE antenna elements are passive and do not require a DC power supply.

The two WiFi/BT cables should be connected to the corresponding wireless antenna ports of compatible WiFi or Bluetooth equipment. The supported frequency range of each antenna path must be matched with the connected module before installation.

The GNSS cable must be connected to an active-antenna-compatible GNSS receiver input. The receiver should provide a 3-5V DC bias voltage through the coaxial cable to power the integrated GNSS low-noise amplifier.

The standard TX-G98 supports GPS L1 and BDS B1 signals. It does not perform positioning or provide RTK capability by itself. Actual positioning performance depends on the connected GNSS receiver, software, satellite environment, installation position, and overall system design.

The GNSS, LTE 1, LTE 2, WiFi 1, and WiFi 2 cables must be clearly identified before connection. Connector appearance alone should not be used to determine RF port assignment.

The antenna should be installed in a suitable position with a clear satellite view for the GNSS section. Nearby metal structures, electronic modules, interference sources, and improper cable routing may affect antenna performance.

RF performance and isolation between the five antenna paths should be verified in the final equipment and installation environment before volume production.
