Antennas

Why Add an External Antenna to Your 4G/5G Router?

The performance of your cellular router depends heavily on signal quality. In many real-world installations, routers are placed in locations where mobile signal is weak or blocked—inside steel kiosks, electrical cabinets, basement rooms, data enclosures, or even the metal base of a CCTV tower.

Even routers supplied with built-in antennas or screw-on whip antennas may suffer degraded speeds, unstable connections, or frequent dropouts in such environments.

External antennas solve this problem by allowing the router to be connected to an antenna mounted in a location with significantly better signal quality—such as the roof, external wall, or mast pole.

Common Installation Scenarios:

• CCTV towers with metal bases that block signal

• Industrial plant rooms with reinforced concrete or shielding

• Comms cabinets and kiosks in solar or utility deployments

• Temporary buildings and cabins with foil-lined walls

• Vehicles or trailers requiring stable mobile internet

Our Range of 4G and 5G Antennas

We stock a wide range of antennas to suit every installation environment and router configuration.

🔩 Magnetic Mount Antennas

• Excellent for buildings with poor indoor reception

🏠 Roof Mount & Pole Mount Antennas

• Positioned at high elevation for maximum signal quality

• Common in CCTV, remote monitoring, and solar projects

• Compatible with brackets, clamps, and rooftop masts

🔲 Panel Antennas

• Directional for focused signal strength

• Ideal when you know the direction of the nearest mast

• High gain and excellent performance over distance

🚚 Adhesive and Embedded Antennas

• For internal enclosures, kiosks, or small devices

• Slim profile and suitable for concealed or internal installs

We provide single and dual antenna options, with mounting accessories, extension cables, and adapters as needed.

MIMO Technology Explained

📶 What is MIMO?

MIMO stands for Multiple Input, Multiple Output—a wireless technology used to multiply signal paths between the router and the cell tower. Most modern 4G and 5G routers use 2×2 MIMO, 4×4 MIMO, or higher.

Installing the right antenna with the correct number of elements is essential to take advantage of this performance boost.

📡 Types of MIMO Antennas We Stock

✅ SiSo Antennas

• Single Input, Single Output

• Basic antenna, typically for legacy systems or telemetry devices

• Not recommended for modern LTE routers needing high throughput

✅ 2×2 MIMO Antennas

• Two antennas in one housing

• The most common type for 4G LTE routers (e.g. RUT241, RUT360)

• Boosts reliability and data speeds

✅ 4×4 MIMO Antennas

• Four antenna elements

• Required to unlock the full speed potential of many 5G routers (e.g. RUTX50, Robustel R5020)

• Essential for future-proofing and high-capacity sites

Choosing the correct MIMO antenna ensures your router performs at its full capability. Using a single antenna on a 2×2 or 4×4 MIMO router can lead to slower speeds and poor reliability.
