Give your mobile broadband better reception opportunities with Signaflex – a kit containing two log-periodic directional antennas for 2×2 MIMO. Designed for compatible 4G and 5G routers with two external antenna ports, the package includes a shared mounting bracket and two cables with SMA male connectors.
When the router’s built-in antennas provide insufficient reception, external antennas in a better position can make a meaningful difference. Signaflex allows you to position the antennas outdoors and align them towards a suitable base station, while the router remains indoors where it is needed. This suits fixed installations in homes, holiday properties and business premises.
The two antennas work together for 2×2 MIMO, allowing a compatible router to use two antenna connections and multiple signal paths in the mobile network. The kit is intended for installation with horizontal and vertical polarisation. A shared bracket keeps both antennas together and supports positioning and alignment.
The antenna kit covers 698–960 MHz and 1710–3800 MHz. These ranges include frequencies around 700, 800, 900, 1800, 2100, 2600 and 3500 MHz. This provides coverage for several 4G bands and for 5G within the specified ranges, provided that the router and network support the relevant bands.
Stated antenna gain is 9–16 dBi per antenna, depending on frequency. Directional reception and careful alignment can help improve signal quality and connection stability. Under favourable network conditions, this can also contribute to higher data speeds.
Choose two five-metre cables or two ten-metre cables, both with SMA male connectors towards the equipment. The five-metre option suits routers positioned close to the antennas, while the ten-metre option offers greater cable routing flexibility. Select the shortest option that reaches your equipment to limit cable signal loss.
Signaflex is a practical choice when you want two directional antennas, cables and a shared mounting bracket in one package, ready for a fixed external MIMO antenna installation.
✅ Benefits

- Two cable length options. Choose 2 × 5 m or 2 × 10 m.
- SMA male connectors on both cables. For compatible SMA female antenna ports.
🎯 Ideal for
- 4G and 5G routers with two compatible SMA female antenna ports.
- Homes and holiday properties with weak mobile reception and a suitable outdoor antenna position.
- Fixed broadband installations where the antennas can face a suitable base station.
- Installations operating within 698–960 and 1710–3800 MHz.
- Users seeking two antennas, cables and a shared bracket in one kit.
🔧 Connection and use
Check that your router supports an external 2×2 MIMO antenna installation, has two compatible antenna ports and operates within the specified frequency ranges.
Install both antennas on the supplied shared bracket according to the product’s installation instructions. The kit is intended for horizontal and vertical polarisation. Secure the assembly to a stable mast or pole.
Connect both SMA male connectors to the router’s matching antenna ports. Enable external antennas in the router settings if required.
Align the antennas towards the same suitable base station and adjust gradually. Allow the router to update its readings between adjustments. Compare signal quality, speed and stability before securing the bracket.
Choose 5 or 10 metres per cable to suit your installation. Protect exposed connections against moisture, provide cable strain relief and avoid sharp bends and unnecessary extensions.
