Give your mobile broadband better reception opportunities with ATK-20 – a 20-element multiband directional antenna for fixed outdoor installation. It includes a 10-metre antenna cable with an SMA male connector and an adjustable mast bracket for installation on a suitable pole.
When the router’s built-in antennas provide insufficient reception, an external antenna in a better position can be a valuable step towards a more stable connection. ATK-20 allows you to move the reception point outdoors and align the antenna towards a selected base station, while the router remains where it is needed inside the building.
The 1.7-metre aluminium construction with 20 elements provides a directional pattern. Specified beamwidths are 25° horizontally and 26° vertically, making careful alignment important. By testing different directions and monitoring the router’s signal readings, you can identify the position that gives the best results at your location.
The supplied information lists support for 800, 900, 1800, 2100 and 2600 MHz. The antenna is intended for compatible mobile communication equipment using these frequencies and can therefore serve several bands within a fixed 4G installation. It can also be used with compatible 2G and 3G equipment where those networks remain available.
The included 10-metre cable with SMA male connector provides flexibility when the antenna needs to be positioned away from the router. An adjustable mast bracket is supplied, allowing the antenna to be aligned and secured. An existing antenna pole may offer a practical mounting point if it is stable and has sufficient space.
ATK-20 suits users who want to optimise a fixed broadband installation in a home, holiday property or business premises. Correct frequency matching, positioning and alignment can help improve signal quality and connection stability. Actual speeds also depend on network load, cable losses and router capabilities.
✅ Benefits
- 20 elements for directional reception. Can be aligned towards the base station that delivers the best results.
- Support for several mobile bands. Listed frequencies include 800, 900, 1800, 2100 and 2600 MHz.
- External antenna positioning. Allows you to find a better outdoor reception point.
- 10-metre antenna cable included. Supports installation away from the equipment.
- SMA male connection to the router or modem. For compatible SMA female antenna ports.
- Adjustable mast bracket supplied. Supports mounting and accurate alignment.
- Aluminium construction. An elongated antenna for fixed outdoor installation.
🎯 Ideal for
- Homes and holiday properties with weak 4G reception on one of the listed mobile bands.
- Fixed mobile broadband installations where the antenna can face a suitable base station.
- Compatible Huawei routers and other routers or modems with matching frequency support and an SMA female antenna port.
- Locations with space for a 1.7-metre directional antenna.
- Mounting on an antenna mast or wall-mounted pole.
🔧 Connection and use
Check the mobile bands used at the installation site and confirm that both the antenna and router support them. Also check that the equipment’s antenna port accepts an SMA male connector.
Install the antenna on a stable pole using the adjustable mast bracket. For the specified vertical polarisation, the antenna elements must be upright. Choose a location with the clearest practical path towards the base station.
Connect the 10-metre cable to the equipment. Enable external antennas in the router settings if required.
Adjust gradually, for example in approximately 10-degree steps, waiting up to one minute between adjustments. Compare signal quality, speed and stability before securing the final position.
The antenna provides one cable connection. A router installation requiring two external antennas for MIMO needs an additional suitable antenna.
Protect exposed connections against moisture, provide cable strain relief and avoid unnecessary extensions.
