18dBi 5Ghz Dual Polarised Horn Antenna – Precision Power for High-Speed Wireless Networks

When high performance, interference reduction, and signal accuracy matter most, the 18dBi 5Ghz Dual Polarised Horn Antenna rises to the challenge. Engineered for advanced outdoor wireless networking, this antenna is ideal for Wireless Internet Service Providers (WISPs) and high-demand enterprise installations. It combines 18 dBi of focused gain with the efficiency of dual polarization, delivering improved throughput, lower latency, and reduced signal noise in busy RF environments.

If you’re looking to improve your network’s coverage, capacity, and stability—especially in congested environments—the 18dBi 5Ghz Dual Polarised Horn Antenna operating on the 5Ghz frequency band is a reliable solution.

Key Features

• 18 dBi high-gain for long-range signal performance

• Dual-polarization for cross-polar interference reduction

• Designed for 5Ghz wireless operations (802.11a/n/ac)

• Built tough for all-weather, outdoor deployment

• Precision beam shaping via horn design

• Ideal for WISP backhaul, PTP, and PTMP applications

Focused High-Gain Coverage

The standout feature of this horn antenna is its 18dBi gain, which boosts signal strength and transmission range. Higher gain equates to greater efficiency over distance, making this antenna perfect for long-range, point-to-point (PTP) or point-to-multipoint (PTMP) applications. With a focused radiation pattern, it minimizes RF spillover and ensures your wireless signal reaches exactly where it’s needed.

Unlike traditional sector antennas that may spread their energy too broadly, this 18dBi 5Ghz horn concentrates the beam tightly, offering a clean, interference-resistant signal that’s both stable and fast.

5Ghz Operation for Modern Wireless Demands

Operating in the 5Ghz spectrum, this antenna supports high-speed wireless networking using standards like 802.11a/n/ac. The 5Ghz band is favored for its ability to transmit data at faster rates and handle dense traffic better than the crowded 2.4GHz band.

The 18dBi 5Ghz frequency band is ideal for:

• High-definition video streaming

• Voice-over-IP (VoIP)

• Cloud access and large file transfers

• Low-latency surveillance feeds

• Mesh and backbone network links

With cleaner airspace and less interference from household devices, your network stays more consistent and responsive, even in busy RF environments.

Dual Polarization = Double the Performance

What sets this antenna further apart is its dual-polarized design, meaning it can transmit and receive signals on both horizontal and vertical planes. This not only improves link reliability but also reduces polarization mismatch loss—a common problem in single-polarized setups.

Dual-polarization is especially beneficial in multipath environments, where signals reflect off buildings, trees, or terrain. It enhances signal reception and throughput, especially when paired with MIMO-capable radios.

This makes the 18dBi 5Ghz Dual Polarised Horn Antenna perfect for challenging deployments in urban, hilly, or mixed terrain zones.

Built for Harsh Outdoor Conditions

This antenna is designed for real-world, rugged use. Whether you’re mounting it on a tower, rooftop, mast, or pole, it’s built with UV-stable, weather-resistant materials that can stand up to heat, cold, rain, wind, and snow. The heavy-duty housing and robust construction ensure long-term durability without performance degradation.

• IP-rated weatherproof enclosure

• Wind survival: Up to 150 mph (depending on installation)

• Resistant to corrosion, temperature swings, and UV damage

Rain or shine, heatwave or storm, this antenna keeps delivering.

Compact Horn Design for Precision and Simplicity

The horn design isn’t just a visual upgrade—it’s a functional revolution in wireless performance. Horn antennas are known for their symmetrical beam patterns, minimal side lobes, and superb RF isolation. These features help avoid interference, increase network density, and eliminate performance-robbing signal bleed.

This makes horn antennas a popular choice for dense deployments, such as urban WISP sectors, where multiple radios are operating in close proximity.

Plus, horn antennas tend to be smaller and lighter than their dish or sector counterparts—making mounting, alignment, and maintenance easier for field engineers.

Ideal for WISP and Enterprise Applications

The 18dBi 5Ghz horn antenna is the go-to option for:

• Wireless ISPs (WISPs): For base station sector coverage, backhaul, or client deployments

• Point-to-Point Bridging: Connecting buildings, towers, or distant remote sites

• Smart Cities and IoT: Reliable backhaul for sensor networks or public Wi-Fi

• Surveillance and Security: Sending HD video over long distances with zero lag

• Outdoor Event Networking: Deploy temporary high-speed networks at festivals or concerts

Whether you’re building a new wireless network or upgrading an aging one, this antenna provides the reliability, efficiency, and scalability to grow with your needs.
