Scaling Your WISP Network: When to Choose 20° vs. 30° Horn Antennas

As Wireless Internet Service Providers (WISPs) grow, they inevitably face a "density wall." Adding more subscribers to a single tower using traditional 90° or 120° sector panels often leads to self-interference and spectrum exhaustion. The solution lies in network densification using precise, Narrow angle horn antenna technology.

But how do you choose the right beamwidth? For most high-performance Point to multipoint antenna deployments, the choice comes down to 20° versus 30° models. As a professional China antenna manufacturer, BBT Antennas breaks down the technical differences to help you optimize your deployment.

To maximize spectrum efficiency in 2026 and beyond, the shift to narrow beamwidths is inevitable. By integrating 20° and 30° broadband horns into your network, you ensure higher throughput, lower latency, and a path to future frequency expansions.

For Wireless Internet Service Providers (WISPs) globally, the greatest enemy isn't distance—it's noise. As the 5GHz and 6GHz spectrums become increasingly crowded, traditional sector antennas often struggle with side-lobe interference, leading to a higher noise floor and degraded packet performance. 20° wisp horn
