Flexible Infrastructure for Modern WISP Networks

Wireless networks are evolving rapidly. Higher subscriber density, growing bandwidth demand, and the expansion of the 6 GHz band require smarter infrastructure decisions.

RF elements® 4×4 Wideband Horn Antennas are designed to give operators unmatched flexibility to adapt.

What Makes 4×4 Wideband Horns Unique?

Traditional array sector antennas provide higher boresight gain at the expense of narrower elevation beam width and inherent side lobes. While this performance may be attractive in early-stage deployment, these solutions reach their limits in dense environments. At the same time, spectrum usage is expanding from 5 GHz into 6 GHz.

4×4 Wideband Horn Antennas address both challenges by offering:

• 4×4 capability for higher capacity radios in dense sectors
• Wideband frequency support (5 GHz + 6 GHz)
• Controlled beam patterns for improved interference management (better noise isolation)
• Future-ready infrastructure without the need for antenna replacements

This combination enables scalable network growth while protecting existing tower investments.

More Capacity Options

4×4 Wideband models include:

• 4×4 AH60WB - 60° Azimuth, 25° Elevation
• 4×4 AH90WB - 90° Azimuth, 25° Elevation

4×4 Wideband Horns enable:

• Higher throughput per sector
• Improved spectral efficiency
• Better utilization of modern 4×4 radios
• Reduced vertical tower congestion
• Provide additional mounting points for wireless equipment (with Smart Bracket)

Deployment Versatility

4×4 Wideband Horns support multiple deployment strategies:

• Using part of the antenna for independent carrier sectors
• Combining failover and primary coverage in compact layouts
• Integrating multi-band radios without additional mounting complexity

This flexibility makes them suitable for both high-density urban sites and rural expansion deployments.

Wideband Spectrum Flexibility: 5 GHz and 6 GHz

Spectrum flexibility is becoming essential. Worldwide adoption of 6 GHz bands is unstoppable, and dual-band deployments are increasingly common.

Future wideband technologies

Antennas are ready for next-generation WiFi7 based radios. Operators can deploy 5 GHz or 6 GHz today and migrate to full 
5 + 6 GHz wideband in the future - without replacing antennas. This reduces long-term costs and simplifies network planning.

Smarter Sector Design

The controlled radiation pattern of Horn technology enables clean beam shaping with naturally attenuated side lobes. This improves sector isolation and enables more effective frequency reuse.

In dense WISP environments, interference is the primary performance constraint. 4×4 Wideband Horns reduce collected noise, improving real-world signal-to-noise ratio (SNR).

The result is more stable modulation rates and predictable performance under load.

Built for Long-Service Life of Critical Infrastructure

RF elements® Wideband antennas are designed and manufactured in the EU. They are built from extruded aluminum for long-term durability in harsh environments. Antennas are engineered for corrosion resistance and reliable outdoor operation.

RF elements® Wideband Antennas are designed to stay on the tower through multiple radio upgrade cycles.

A Future-Ready Solution

4×4 Wideband products represent a forward-looking solution aligned with 6 GHz expansion and WiFi7 evolution. They offer:

• Reduced upgrade risk
• Simplified inventory through wideband compatibility
• Long-term infrastructure stability

As network demand continues to grow, performance and flexibility become the deciding factors.

4×4 Wideband Horn Antennas deliver both - today and into the future.
