The CD2405 2.4 GHz ISM band antenna offers an omnidirectional pattern enabling optimum network configuration. The patented PCB-based design delivers consistent VSWR, pattern and tilt characteristics across the entire operating bandwidth, by removing manufacturing variations found in other, more traditional mechanical collinear designs.

It is covered with black fibreglass radome, matching black cap and delrin connector housing, making it ideal for outdoor applications. Includes an integrated N male connector for terminal mounting, or mounting to N Female bulkheads. Also available in a high gain 8.5 dBi version.

  • 2.4 GHz WiFi antenna
  • Tightly controlled radiation patterns for optimum coverage
  • Integrated N male connector at base
  • Patented PCB design for optimum RF pattern stability
  • Small unobtrusive design
