18 dBi Yagi Directional AntennaLong-range antenna for WiFi / wireless networks.

  • For the fixed shipping fee of $9: We ship by FedEx Ground.
  • Data Alliance's high-quality soldered terminations of Type-N connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.

Directional antenna concentrates signal strength in a narrow beam for maximum signal strength and performance over long distances. The narrow concentration enables excellent distance, could transmit/receive signal over a distance of 14 miles. Can serve as access point's antenna, or attach to client/card or bridge, and point directly at the access point.

Compatibility with wireless standards & applications: This directional antenna's range of frequency band compatibility in the 2.4 ~ 2.5GHz frequency band range, its its excellent low broadband VSWR at < 1.5, and impedance matching to 50 Ohm gear, makes it suitable and compliant for all the following applications:

Standard type N-female coax connector on The pigtail: Fits items that have a N-male connector.

GENDER DETERMINATION: Gender of N is counter-intuitive: Please observe picture & note it is correct.The gender is referring to the pins inside-not the threads. N-female has threads on outside. Click here for more details regarding N-connector gender determination.

    Many antennas do not perform as advertised. While we did not have access to an anechoic chamber to verify the received dBi; we did conduct a comparison test between a known 14.5 dBi antenna and this product. Very surprisingly, it does appear to provide a 4 dBi improvement. It also swept with less than 1.5 VSWR across the advertised band.
    In fact I am ordering another one for comparison-hopefully it performs as well as our original antenna!
