RFI CD2409 8.5dBi 2.4GHz ISM Collinear Antenna


Key Features


  • Full 2.4-2.5GHz band

  • Suits 802.11b/g/n WiFi, Bluetooth, and other ISM applications

  • Ideal for extending the range of outdoor WiFi access points

  • This 2.4 GHz ISM band antenna offers an omnidirectional pattern enabling 360° optimum network configuration

  • The patented PCB design delivers superior pattern stability across the entire 2.4-2.5GHz band avoiding inherent pattern tilting common in more traditional collinear designs

  • Includes an integrated 'N' type male connector for easy mounting.




  • Perfect for covering large outdoor areas

  • This antenna is often used to cover football grounds, stadiums, music festivals, where access points/routers are spread distances apart

  • The 13° vertical broadcast angle means that maximum transmission power is directed horizontally, with little power wasted transmitting into the air or ground below.
