When Size Really Matters: Maximum Performance at a Distance
For directional radio links, there's a simple physical law: the larger the antenna's surface area, the more signal can be captured and bundled. The Ubiquiti AF-5G34-S45, with its impressive 105 cm diameter, is a true powerhouse. It bundles the 5 GHz signal so strongly that you can transmit high data rates even over extreme distances of 50, 80, or even 100 kilometers. This makes it the ideal choice for critical long-range backhaul connections, where every kilobit counts.
Interference-Free with Slant 45: Your Signal Stays Clean
Especially with long-range links, one often picks up a lot of 'noise' and interference from the environment. The innovative Slant 45 Polarization of the AF-5G34-S45 is a decisive advantage here. By operating in an 'X'-format instead of the conventional '+' format, the antenna filters out a large part of the interference from foreign WiFi networks. This significantly improves the Signal-to-Noise Ratio (SNR) and ensures a more stable and reliable connection, even in densely populated areas.
Precision That Pays Off: A Link Like a Rock in the Surf
With an extremely narrow beamwidth of only 3 degrees, this antenna behaves like a sniper rifle. This sniper precision means your signal is highly focused. While alignment requires some patience and stable mounting, once the link is established, it is extremely difficult to jam and offers high eavesdropping security. A perfect solution for sensitive data transmissions and critical infrastructures.
Mounting and Stability: How to Perfectly Align Your Link
Due to its size and the associated wind load, the AF-5G34-S45 requires a stable mast. However, the included bracket is specially designed for this and features fine adjustment, which helps you precisely align the narrow beam. This ensures that your link functions optimally and remains stable even in adverse weather conditions. The robust construction guarantees wind resistance of up to 200 km/h.
