Military Antenna Omni Directional Antenna 5150-5850MHz 20×400

In today’s increasingly congested wireless spectrum, the 5.15–5.85GHz band has become a critical resource for long‑range, high‑speed communication. Specifically optimised for this band, the BGS-AN5850-20400G omnidirectional antenna delivers stable, high‑efficiency RF front‑end performance for point‑to‑multipoint links, Wi‑Fi backhaul, security surveillance, and industrial wireless networks – thanks to its outstanding electrical characteristics and rugged outdoor‑grade construction.

Exceptional Performance – Unleashing the Band’s Potential

• Broadband Coverage, True Omnidirectional Pattern
  Full operating frequency range from 5150 to 5850MHz, with 360° horizontal radiation and a narrow vertical beamwidth of only 11~15°. Regardless of the device’s position around the antenna, consistent signal strength is achieved, while the narrow vertical lobe concentrates energy to increase range and suppress interference.
• High Gain & High Efficiency
  Typical gain: 6.5–8dBi. Measured data shows a gain of 7.6dBi at 5500MHz with an efficiency of 80.5%; average efficiency across the full band is approximately 76% (typical). Higher gain means stronger transmit and receive capability – ideal for medium‑distance wireless bridging or as a base station antenna for coverage.
• Low VSWR & High Power Handling
  VSWR < 2.0 ensures minimal reflection loss in the RF chain. Maximum input power: 50W, making it compatible with high‑power access points, bridges, and private radio equipment.
• Linear Polarisation – Perfectly Matched
  Linear polarisation works seamlessly with the vast majority of 5GHz wireless devices (e.g. 802.11ac/ax bridges, CPEs, base stations) – no additional polarisation adjustment is required.

Rugged & Durable – Built for Harsh Environments

• Fully Sealed Fibreglass Radome
  Made of high‑quality fibreglass – UV‑resistant, ageing‑resistant, and low dielectric loss. Long‑term outdoor use without deformation or fading.
• Wide Temperature Range & Wind Resistance
  Stable operation from -40℃ to +80℃; rated wind speed 36.9m/s (approximately Beaufort scale 12). Reliable performance under heavy rain, extreme heat, and freezing conditions.
• Integrated DC‑Grounded Lightning Protection
  Internal DC grounding (Lightning Protection: DC Ground) effectively diverts induced lightning currents. When used with an external surge arrestor, system reliability is greatly enhanced.

Typical Applications

• 5GHz Wireless Bridging & Backhaul
  Point‑to‑multipoint backhaul for campuses, farms, river courses, forest fire prevention, etc. A single antenna covers 360°, serving multiple remote stations.
• Outdoor Wi‑Fi Coverage
  As the antenna for outdoor APs in large plazas, stadiums, scenic areas, ports, etc., achieving wide‑area, shadow‑free coverage while minimising interference from upward radiation.
• Surveillance & Video Transmission
  Used with 5GHz digital microwave or COFDM equipment to provide high‑definition video backhaul for fixed or mobile surveillance points.
• Industrial IoT & Private Networks
  Ideal for mining areas, substations, automated production lines, and other industrial environments that demand highly reliable, interference‑resistant wireless connections.
