Product Overview
Dual 4G and GNSS Functions in One Housing-This GNSS combo antenna combines 4G communication and GNSS positioning in a single sealed housing, allowing one mounting point instead of two separate antennas. The compact design simplifies installation while keeping both RF paths working independently. It is a practical choice for a 4G GNSS combo antenna for vehicle tracking, fleet management systems, and telematics equipment.
Fiberglass Housing for Reliable Outdoor Use-The antenna features a fiberglass radome that withstands UV exposure, temperature changes, and outdoor conditions over long-term operation. With a sealed housing and protected cable outlet, this Fiberglass 2 in 1 antenna helps prevent moisture issues in vehicle and outdoor installations.
Solid Copper Radiator for Stable Performance-A solid copper radiator is used inside the antenna to maintain consistent tuning and RF performance during vibration, temperature changes, and extended use. Compared with spring-type elements, the copper structure keeps its shape better and helps maintain stable signal performance, which is important for an Outdoor 4G GNSS antenna used in tracking applications.
Flexible Cable and Connector Configuration-The standard version comes as a 2 cable 4G GPS BDS antenna with RG174 coaxial cable and SMA male connectors, matching many commonly used tracking modules. Cable length, connector type, and cable specifications can be adjusted according to different device designs and installation requirements.
Secure Mounting for Vehicle Installations-The threaded mounting base with nut and washer provides a firm connection for vehicles and outdoor equipment where vibration resistance is required. Combined with waterproof construction and 4G/GNSS dual functionality, this antenna is suitable for fleet tracking, trailers, and remote monitoring systems.

Application
Vehicle Tracking & Telematics Systems-A GNSS combo antenna is commonly used in vehicle tracking systems where both cellular communication and positioning are required in one installation. This 4G GNSS combo antenna for vehicle tracking combines 4G and GPS/BDS functions in a single housing, helping reduce installation space and simplify cable routing. With a sealed structure and independent RF paths, it is suitable for fleet management, telematics units, and commercial vehicles that need stable connectivity during long-term operation.
Vehicle Signal Boosters and Communication Equipment-For vehicle communication systems, the external antenna needs to maintain stable reception while operating in different directions and outdoor conditions. This antenna supports wideband 4G communication frequencies and can be integrated with vehicle boosters, navigation equipment, and wireless terminals. The combined design allows one installation point to support both communication and positioning requirements.
Asset, Trailer and Remote Tracking Applications-Trailers, containers, generators, and other mobile assets often require antennas that can operate reliably with minimal maintenance. The rugged fiberglass housing and through-panel mounting design make this Fiberglass 2 in 1 antenna suitable for equipment exposed to vibration, weather changes, and outdoor environments. The dual-branch configuration keeps the cellular and GNSS signals independent, helping tracking devices maintain reliable communication and positioning.
Outdoor Cabinets and Fixed Monitoring Systems-Remote monitoring equipment, RTUs, gateways, and outdoor cabinets often need both wireless communication and positioning functions in a compact installation space. As an Outdoor 4G GNSS antenna, this model can be mounted through an enclosure wall while keeping the electronics protected inside the cabinet. The weather-resistant fiberglass housing helps ensure stable operation in outdoor locations with temperature changes and continuous exposure.
Agricultural, Construction and Industrial Equipment-Heavy equipment used in agriculture, construction, and industrial environments requires antennas that can handle vibration while maintaining signal stability. The solid copper radiator design helps keep consistent RF performance, while the secure mounting structure provides reliable installation compared with adhesive mounting methods. With a 2 cable 4G GPS BDS antenna configuration, the cellular and GNSS connections can work independently for applications such as machine tracking, navigation, and positioning systems.
FAQ
Q1. What frequency bands does this GNSS combo antenna support? Can it be customized?
Yes, and it is built to order. The 4G branch covers 700–2700 MHz and the GNSS branch covers GPS L1 and BeiDou B1. Both GNSS signals are single-frequency, so this suits tracking and telematics rather than RTK survey work. Send us your LTE bands and GNSS constellations and we will confirm the configuration before production.
Q2. Why does this antenna have two cables, and can the connectors be changed?
Two feeds keep the LTE and GNSS paths apart, so the modem and the positioning receiver never share one path. Standard is a 2 in 1 antenna with two RG174 leads and SMA male connectors; connector type, cable spec and length can all be changed to suit your tracker. Keep the runs short, though: RG174 loss climbs fast at 2700 MHz.
Q3. Is this GNSS combo antenna suitable for fleet tracking applications?
Yes, this is a common choice for vehicle tracking. Telematics boxes, fleet management systems and commercial vehicles run the same 4G plus GNSS pairing. At install, keep it clear of metal panels and roof racks, route cables away from high-current wiring, and leave a drip loop so water cannot run down into the mounting hole.
Q4. Does the fiberglass housing require maintenance for outdoor use?
Very little. This 2 in 1 antenna is sealed against moisture and UV, so there is nothing to repaint and no radome to replace on a schedule. The hardware is what needs attention: check the mounting bolts and the connectors once or twice a year, since the connector is usually the first thing to fail on an outdoor install.
