## Summary description

Directional Yagi antenna ALFA AYA-4G-18 designed for 4G LTE signal reception and transmission. Provides 18 dBi gain for improved cellular connectivity in areas with weak coverage. Intended for outdoor installation to extend mobile broadband range and increase signal stability for routers, modems and LTE gateways.

## Long description

The Yagi Antenna ALFA AYA-4G-18 is a directional outdoor antenna designed to improve 4G LTE reception and transmission. With 18 dBi gain, this antenna focuses cellular signals to extend mobile broadband range and increase stability for routers, modems and LTE gateways. It is intended for external mounting on poles or walls to capture distant base station signals in areas with weak coverage.
Advantages
The antenna delivers high directional gain to increase signal strength and reduce packet loss over cellular links. Its focused radiation pattern helps reject interference from unwanted directions, improving throughput and connection reliability. The robust construction is suitable for outdoor exposure and mounting hardware allows alignment toward target cell towers for optimal performance.
Suitable for
Boosting 4G LTE connectivity for home or small office routers and gateways
Improving mobile broadband reception in rural or fringe coverage areas
Pointing toward a known cell tower to stabilise throughput and reduce dropouts
Outdoor installations on poles, masts or building exteriors
When it may not be suitable
This directional Yagi antenna is not ideal when signals arrive equally from multiple directions or when users require omni-directional coverage around a site. It also may not be appropriate for indoor-only setups because it requires outdoor mounting and clear line-of-sight or near-line-of-sight to the target cell tower for best results.
Key specifications
Frequency range: compatible with common 4G LTE bands (cellular frequency support depends on router and network)
Gain: 18 dBi
Radiation pattern: directional (Yagi)
Mounting: pole or wall mountable with included brackets
Weather resistance: designed for outdoor use with durable materials
How to use
Mount the antenna outdoors on a pole or wall where it has an unobstructed view toward the nearest cell tower. Use the adjustable bracket to align the antenna for maximum signal level as shown by your router or signal meter. Connect the antenna to your router, modem or LTE gateway using a suitable coaxial cable and compatible connector; ensure connectors are tightened and weatherproofed at entry points. After installation, test signal strength and adjust orientation in small increments to find the best reception.
What to consider before purchase
Check compatibility with your router or modem connector type and the supported cellular frequency bands in your area
Confirm that outdoor mounting and the required pole or wall space are available
Plan for appropriate coaxial cable length and weatherproofing accessories for external routing
Usage recommendations
Position the antenna as high as practical and align it toward the strongest nearby cell tower. Use low-loss coaxial cable for longer runs and seal outdoor connectors to prevent moisture ingress. If signals are still weak, consider pairing this directional antenna with a second antenna for MIMO-capable routers if supported.
