Your Bridge to the Distance: WiFi Over Kilometers
The ALFA AGA-2424T is no ordinary Antenna – it's your personal data highway through the air. With a massive gain of 24 dBi, this Antenna specializes in establishing Point-to-Point (PtP) or Point-to-Multipoint (PtMP) connections over extreme distances. Whether you want to Network two company buildings, connect an IP Camera on a remote part of your property, or simply bring internet to a neighbor's house: this directional Antenna provides the necessary power and stability. For such a WiFi Bridge, you need an identical or similarly powerful antenna at both locations to guarantee a symmetrical and reliable connection.
Precision Instead of Dispersion: Maximum Signal Quality
The key to long range lies in the extreme bundling of the signal. With a very narrow beamwidth of only 10° horizontal and 14° vertical, the AGA-2424T works like a spotlight. This has two crucial advantages: Firstly, the entire transmission power is precisely focused on your target, minimizing signal loss. Secondly, interference from neighboring WiFi networks is effectively filtered out. The result is a clean, interference-free connection with maximum data throughput. However, this precision requires millimeter-accurate alignment with the remote station and an absolutely clear line-of-sight without obstacles like trees or buildings.
Built for Any Weather: Robust Outdoor Construction
An outdoor antenna must be able to withstand the elements. ALFA Network relies on an uncompromisingly robust construction for the AGA-2424T. The grid is made of solid die-cast aluminum, sealed with a UV-stable, light gray powder coating. This protects not only against corrosion but also against fading from the sun. With an operating temperature range of -40°C to +85°C, this antenna is designed for year-round use in any climate zone. Proper grounding is also essential to protect your connected electronics from overvoltages, e.g., during thunderstorms, providing excellent Lightning Protection.
Connection & Compatibility: What You Need to Know
The antenna features a professional N-female connector. To connect it to common WiFi USB Adapters or WiFi Routers (which often have an RP-SMA connector), you need a suitable, low-loss Antenna Cable, a so-called Coaxial Pigtail. Make sure to keep this cable as short as possible to minimize signal attenuation. You can mount the antenna for both vertical and horizontal polarization. It's only important that both Antennas of a wireless bridge are identically aligned (polarized) to achieve the best possible performance. Assembling the two grid halves is straightforward; the real challenge lies in precise alignment on the mast, utilizing appropriate Antenna Mounting Accessories.

Frequently Asked Questions (FAQ)
Do I really need two of these Antennas for a long-range WiFi Bridge?
Yes, absolutely! For a stable point-to-point connection, you need a powerful directional antenna like this at both ends, meaning at both the transmitting and receiving locations. This is the only way to ensure your connection runs at full power in both directions.
Which cable do I need to connect the antenna to my WiFi USB Adapters?
You need a high-quality, low-loss Antenna Cables. The antenna has an N-connector (female). Check which connector your WiFi device has – it's often RP-SMA. You'll then need a suitable adapter cable, for example, an N-male to RP-SMA-male connector. Our tip: Keep the cable as short as possible, because every extra centimeter steals signal strength!
Can I simply boost my WiFi in the garden with this antenna?
No, it's absolutely the wrong choice for that. Imagine the antenna like a laser pointer: it focuses the signal extremely strongly in just one direction. To provide your garden with comprehensive WiFi coverage, you need an Omni-Directional Antennas that distributes the signal like a light bulb in all directions.
Do I really need to ground the antenna when mounting it outdoors?
Absolutely! Proper grounding is a must for any outdoor antenna. It not only protects the antenna but, more importantly, your expensive Network devices from damage due to static electricity or nearby lightning strikes. Safety is clearly the priority here!
Can I mount the antenna both horizontally and vertically?
Yes, both are possible. You can determine the polarization yourself through the mounting method. This is important to minimize interference. However, make sure that your counterpart, meaning the second antenna, has the exact same orientation – otherwise, they'll 'talk past each other'.
Is assembling the grid antenna complicated?
The mechanical assembly is child's play. You simply screw the two grid halves and the signal emitter together. The real challenge comes afterward: the millimeter-precise alignment of the antenna to your target. Take your time with this, because it determines the quality of your connection!
