Product Overview
Combo MIMO Mobile GNSS WiFi Roof Antenna 5-in-1
Product features:
The FS-G26 houses five antenna elements in one compact roof-mounted dome: a 2×2 cellular pair for 4G and 5G NR Sub-6 GHz, an active GNSS element at 1575.42 MHz, a 2.4 GHz WiFi element and an NB-IoT element. All five cables exit through a single threaded mounting stud, keeping roof installation simple with just one mounting hole. The cellular, WiFi and NB-IoT elements typically provide around 3 dBi gain, while the GPS element uses a built-in LNA with approximately 28 dB gain. We can adjust the frequency bands, cable lengths and connectors (SMA, FAKRA or N-type) to fit your equipment. For fleet vehicles running routers, trackers and cameras, this Vehicle Tracking Antenna offers a practical way to combine several wireless connections in one housing. The MIMO combo antenna can also be configured for selected frequency bands, including 617 MHz and 3.8 GHz. Share your equipment’s port layout with us, and we’ll match the cable arrangement to your setup.

Application
- Fleet and Telematics Systems-Fleet vans and light trucks often need antennas for vehicle tracking, cellular routers and onboard cameras. A multi-function combo antenna brings several wireless connections into one roof-mounted unit, reducing the need for multiple roof holes and separate antenna installations. For fleet upgrades, the antenna also needs to fit the vehicle’s roof and connect easily with the existing tracking and communication equipment. This makes choosing the right Vehicle Tracking Antenna an important part of the installation.
- Trailers, Containers and Yard Equipment-Trailer and container installations can be a little more complicated, particularly when the roof uses aluminium panels, plywood or composite materials. These surfaces may not provide the ground plane that some antennas need. In such cases, installers may need to fit an additional metal plate beneath the antenna. It’s worth checking the mounting surface before installation, as the grounding arrangement can affect GNSS reception and overall antenna performance.
- Emergency Vehicles and Service Trucks-Emergency vehicles and service trucks often carry cellular routers, WiFi access points, GNSS receivers and other communication equipment. Fitting a separate antenna for each system can quickly use up roof space and make installation more complicated. A combo antenna offers a more compact alternative by bringing multiple RF connections into one housing. Where the router requires multiple cellular antenna ports, a MIMO combo antenna can also be considered, with the port configuration and frequency coverage matched to the equipment.
- Marine, Agricultural and Off-Road Equipment-Boats, agricultural machinery and port equipment often have fibreglass or composite mounting surfaces rather than conventional metal roofs. Since these materials do not provide a metal ground plane, some antenna designs may need an additional metal plate beneath the mounting position. Installers should also check the available mounting space, cable routing and grounding arrangement before fitting the antenna. These details are particularly relevant when one combo antenna handles both cellular communication and GNSS positioning.
FAQ
Q1. What does each of the five cables connect to, and can we customize the colour coding?
The five cables are assigned to GPS, cellular A, cellular B, WiFi and NB-IoT. Each cable has a moulded boot, with the colour coding confirmed on the product drawing before production. For orders of 20 pieces or more, we can adjust the cable sequence, boot colours and connector type on each lead. Just send us the port layout of your router or head unit, and we can match the cable assembly to your setup.
Q2. The specification table lists 28 dBi gain. Is this the actual antenna gain?
No. The 28 dB figure refers to the GPS element’s built-in LNA gain, not the antenna’s passive gain. A passive gain of 28 dBi would require a much larger antenna structure, which is not what this vehicle-mounted dome uses. The cellular, WiFi and NB-IoT elements are low-gain omnidirectional antennas. When checking link performance, look at the actual antenna gain and account for the installation distance and coaxial cable loss. The GPS LNA figure should not be used as the gain value for the other antenna elements.
Q3. Does the GPS element need external power?
Yes. The GPS element is an active GNSS antenna with a built-in LNA. It draws power from the connected receiver through the coaxial cable, so check the receiver’s datasheet for its bias voltage and current requirements. If you want to connect two devices to one GPS antenna, use an active GNSS splitter with the correct DC-pass and DC-block arrangement. A simple T-connector won’t provide the necessary power isolation. If you share your receiver model or bias specifications with us, we can check the power requirements before production.
Q4. Does the cellular section support true MIMO, or does it split one antenna signal into two?
It uses two independent cellular elements, each with its own feed point and coaxial cable. Neither element shares its RF signal with the other, so both can connect directly to the router’s cellular ports for 2×2 MIMO operation. This is what makes it a MIMO combo antenna, rather than a single antenna with a splitter. If your router uses 4×4 MIMO, you’ll need four independent cellular antenna elements, either across two antennas or in a housing designed for four cellular feeds.
