RF Elements Array Sector 5Ghz 20dBi Antenna




RF elements® Array Sector antennas provide exceptional RF performance, colocation capability, ease of installation, and cost efficiency. The antennas feature our patented BackShield™, a frequency selective surface that attenuates the side lobes in the azimuth plane and back radiation, integrated directly in the antenna body. Array Sector 5-20 operates in extremely wide frequency band, has balanced gain in both polarizations, and offers unmatched main lobe stability for superior coverage performance.

  • Introducing The New Array Sector 
    • The new Array Sector series are superior patch array antennas optimized for excellent performance in sectorial coverage and dense cluster applications.
  • Stable Gain Across The Band 
    • The gain of Array Sector antennas remains very stable across an ultra-wide range of frequencies 5150-5850 MHz.
    • VSWR values are excellent across the whole useful spectrum for maximum power delivered from a radio to the antenna.
  • Optimized For Co-Location 
    • Array Sector Antennas feature BackShieldTM, our patented structure that effectively mitigates sidelobes in azimuthal plane and parasitic back radiation.
    • BackshieldTM significantly improves co-location capability in dense cluster deployments.
  • BackShieldTM 
    • BackShieldTM is our patented frequency-selective surface that effectively attenuates back radiation and the side lobes in the azimuthal plane.
    • BackShieldTM is integrated into the antenna structure so there is no need for aftermarket accessory shields.
  • Wide Platform Compatibility 
    • Array Sector Antennas are compatible with all major radios with coaxial connectors (check datasheet for complete list).
    • Array Sector Antennas also feature removable cover protecting the SMA connectors, another feature introduced by RF elements® that became an industry standard.
  • New Antenna Bracket 
    • Array Sector Antennas feature an innovative mounting system composed of minimum parts for quick & easy assembly, installation, and alignment.
    • Stainless steel hardware has black colored anti-friction surface coating to prevent seizing.
  • Durable Build 
    • Solid extruded aluminium body enables Array Sector Antennas endure any weather conditions.
    • We use materials of highest quality: extruded and stamped aluminium, surface coated stainless steel, UV resistant ABS plastic & high density polyethylene.
  • Hardware with Anti-Seize Coating 
    • The Array Sector Antennas have hardware with black-colored anti-friction surface treatment using polymer-based tribological dry coating with sub-microscopic lubricant particles providing effective protection from seizing.
