Ubiquiti AF-5G30-S45: The Noise Killer
Anyone building a wireless link in a city or industrial area knows the problem: The 5 GHz band is crowded. Standard WiFi routers cause interference everywhere.
The AF-5G30-S45 is the solution. In combination with an airFiber 5X radio, it uses a physical trick:
The "Slant 45" Advantage
Normal WiFi transmits like a "plus sign" (+) – vertically and horizontally.
This antenna transmits like an "X" – rotated by 45 degrees.
The effect: Signals from standard WiFi networks are physically attenuated by approx. 3 dB before they even reach the software. This massively improves your Signal-to-Noise Ratio (SNR) and enables higher modulation rates (more speed).
Deep Dish Reflector
The reflector of the dish is deeper than that of standard antennas. This ensures extremely sharp signal focusing (only 5.8° beamwidth) and shields against lateral interference ("noise") better.
Perfect Match for airFiber 5X
The back of the antenna is shaped so you can simply click in an airFiber 5X or 5XHD. The pigtail cables are pre-installed and weather-protected. You don't need any extra tools.
