Maximum 360° Coverage with 15 dBi Performance
If you are looking for an uncompromising solution to provide comprehensive WiFi coverage for a large area, the ALFA Network AOA-2415 is your first choice. This powerful WiFi base station Antenna was specially developed for outdoor use and delivers outstanding transmission and reception performance in the 2.4 GHz frequency band with an impressive gain of 15 dBi. Whether for a public hotspot, supplying a campsite, or illuminating an extensive company premises – this Antenna precisely bundles energy at the horizon to achieve maximum range, making it a top choice among 2.4 GHz Antennas.
Built for Eternity: Weatherproof and Robust
The AOA-2415 is not only powerful but also extremely durable. The Antenna housing (radome) is made of high-quality fiberglass, which reliably protects the sensitive internal technology from rain, snow, UV radiation, and extreme temperatures. The integrated DC short-circuit Lightning Protection offers an additional layer of security for your valuable Network hardware. Thanks to the professional N-connector and the included mounting material, installation on a mast is straightforward, resulting in a permanently stable, weatherproof 15dBi WiFi omni-directional antenna you can rely on. Consider using appropriate Cabling for optimal performance.
Strengths & Notes at a Glance
- Pro: Exceptionally high 15 dBi gain for maximum range.
- Pro: Extremely robust and durable fiberglass construction for all-weather operation.
- Pro: Integrated DC short-circuit Lightning Protection for basic safety.
- Pro: Professional N-Female connector for low-loss, stable connections.
- Note: The very narrow vertical beamwidth of 6° requires exact vertical mounting and is ideal for flat terrain.
- Note: The considerable length of almost 1.5 m creates a high wind load and requires very stable mast attachment.

Frequently Asked Questions (FAQ)
For which application is the ALFA AOA-2415 ideal?
The AOA-2415 is ideal for Point-to-Multipoint applications in the 2.4 GHz band, where a large, flat area needs to be covered with a WiFi signal. Typical use cases include public hotspots, illuminating warehouses, farms, or event venues from a central point, often utilizing a powerful WiFi Access Point.
Do I need a special cable to connect the antenna?
Yes, you need an Antenna Cable with an N-Male connector for the connection to the antenna. The other end of the cable must match the connector of your WiFi Router or WiFi Access Point, which is often an RP-SMA or SMA connector. Ensure you use a high-quality, low-loss, and weatherproof cable so as not to impair the high gain of the antenna.
Can I receive my WiFi signal over several kilometers with this antenna?
Theoretically yes, but practically the range depends on many factors. As a transmitting antenna, it can distribute a WiFi signal widely. As a receiving antenna, it can pick up distant signals, but only if there is a direct line of sight and the other end also has strong transmission power. The narrow vertical angle requires precise alignment for optimal Network performance.
Is the antenna suitable for the 5 GHz WiFi range?
No, the ALFA AOA-2415 is exclusively specified for the 2.4 GHz frequency band (2.4 - 2.5 GHz). It will not function in the 5 GHz band and could potentially damage a 5 GHz device if connected. For 5 GHz applications, specific 5 GHz Antennas are required.
What does 'DC Short' lightning protection mean?
A 'DC Short' or DC short circuit means that the antenna presents a short circuit for direct current. This helps to discharge static charges, which build up due to wind and weather, directly to the ground. It provides basic protection against nearby lightning strikes but does not replace professional, external Lightning Protection.
Does the length of almost 1.50 m affect performance?
Yes, the physical length is directly responsible for the high power gain. For omni-directional WiFi Antennas, gain is often achieved by 'stacking' multiple antenna elements one above the other (collinear arrangement). The more elements, the longer the antenna and the higher the gain – but at the same time, the vertical beamwidth becomes narrower, impacting the overall Network coverage.
